Narrative:

The aircraft was approximately 645000 pounds on touchdown just slightly below maximum landing weight; of 666000 pounds. Due to the heavy weight the approach briefing was to clear the runway at the last exit unless we were in a good position and speed to clear at an earlier exit. After being cleared to land at approximately 2000 ft there were no further messages from the tower to us to indicate any special requirements after landing aircraft touched down on runway 7R. During the landing roll at approximately 100 KTS the tower issued a set of instructions which were interpreted as 'to clear the active runway at intersection east and to expedite the exit as aircraft was behind us on short final.' due to the urgent yet untimely receipt of these ATC instructions as the aircraft was still in reverse thrust and at 100 KTS very close to exit east and the first officer being the handling pilot an immediate xfer of controls was made with no time to question or acknowledge the message by me as I was now the handling pilot canceling reverse; applying brakes watching out for the exit at east. I expedited clearing the active runway 7R at exit east as the ATC had requested. After clearing the active runway 7R I moved the aircraft as far as possible forward on exit east to make sure my aircraft's tail was well clear of runway 7R as I assumed the aircraft behind me was a big jet as ATC could not have cleared any other aircraft to be landing so close after our aircraft a B747-400. ATC then issued instruction 'hold short runway 7L.' our aircraft had halted and was well clear of runway 7L but had technically breached the hold short line of runway 7L. Then to my surprise the aircraft behind us (I believe a dash 8 or small twin) for who I had performed the expediting exit at east from runway 7R was cleared to land on runway 7L. Shortly after ATC asked the dash 8 to go around at approximately 150 ft as technically runway 7L was not clear as we had breached the hold short line. Dash 8 was asked to do a tight circuit and landed on runway 32 a few mins later. Too many instructions from ATC at a very critical phase in the landing roll.

Title: DURING LNDG ROLL AT 100 KTS; CTLR ISSUED INSTRUCTIONS TO A B747-400 TO EXPEDITE TURNING OFF THE RWY DUE TO LNDG TFC ON SHORT FINAL. PLT MADE AN EFFORT TO CLR THE RWY AS INSTRUCTED AND IN DOING SO; CROSSED THE HOLD LINE FOR THE PARALLEL RWY CAUSING A GAR.

Narrative: THE ACFT WAS APPROX 645000 LBS ON TOUCHDOWN JUST SLIGHTLY BELOW MAX LNDG WT; OF 666000 LBS. DUE TO THE HVY WT THE APCH BRIEFING WAS TO CLR THE RWY AT THE LAST EXIT UNLESS WE WERE IN A GOOD POS AND SPD TO CLR AT AN EARLIER EXIT. AFTER BEING CLRED TO LAND AT APPROX 2000 FT THERE WERE NO FURTHER MESSAGES FROM THE TWR TO US TO INDICATE ANY SPECIAL REQUIREMENTS AFTER LNDG ACFT TOUCHED DOWN ON RWY 7R. DURING THE LNDG ROLL AT APPROX 100 KTS THE TWR ISSUED A SET OF INSTRUCTIONS WHICH WERE INTERPED AS 'TO CLR THE ACTIVE RWY AT INTXN E AND TO EXPEDITE THE EXIT AS ACFT WAS BEHIND US ON SHORT FINAL.' DUE TO THE URGENT YET UNTIMELY RECEIPT OF THESE ATC INSTRUCTIONS AS THE ACFT WAS STILL IN REVERSE THRUST AND AT 100 KTS VERY CLOSE TO EXIT E AND THE FO BEING THE HANDLING PLT AN IMMEDIATE XFER OF CTLS WAS MADE WITH NO TIME TO QUESTION OR ACKNOWLEDGE THE MESSAGE BY ME AS I WAS NOW THE HANDLING PLT CANCELING REVERSE; APPLYING BRAKES WATCHING OUT FOR THE EXIT AT E. I EXPEDITED CLRING THE ACTIVE RWY 7R AT EXIT E AS THE ATC HAD REQUESTED. AFTER CLRING THE ACTIVE RWY 7R I MOVED THE ACFT AS FAR AS POSSIBLE FORWARD ON EXIT E TO MAKE SURE MY ACFT'S TAIL WAS WELL CLR OF RWY 7R AS I ASSUMED THE ACFT BEHIND ME WAS A BIG JET AS ATC COULD NOT HAVE CLRED ANY OTHER ACFT TO BE LNDG SO CLOSE AFTER OUR ACFT A B747-400. ATC THEN ISSUED INSTRUCTION 'HOLD SHORT RWY 7L.' OUR ACFT HAD HALTED AND WAS WELL CLR OF RWY 7L BUT HAD TECHNICALLY BREACHED THE HOLD SHORT LINE OF RWY 7L. THEN TO MY SURPRISE THE ACFT BEHIND US (I BELIEVE A DASH 8 OR SMALL TWIN) FOR WHO I HAD PERFORMED THE EXPEDITING EXIT AT E FROM RWY 7R WAS CLRED TO LAND ON RWY 7L. SHORTLY AFTER ATC ASKED THE DASH 8 TO GO AROUND AT APPROX 150 FT AS TECHNICALLY RWY 7L WAS NOT CLR AS WE HAD BREACHED THE HOLD SHORT LINE. DASH 8 WAS ASKED TO DO A TIGHT CIRCUIT AND LANDED ON RWY 32 A FEW MINS LATER. TOO MANY INSTRUCTIONS FROM ATC AT A VERY CRITICAL PHASE IN THE LNDG ROLL.
