Narrative:
Lynns 1 arrival from pgs transition. Issued clearance to descend via STAR las. Level 12000 ft lynns, turning right per FMS to mirot to cross at 11000 ft. Traffic was depicted on TCASII 700 ft low. Controller issued a descent, 'expedite out of 10000 ft for 8000 ft.' moments later, controller issued us a turn to 020 degrees into traffic with already an expected descent. Became a TCASII alert, followed by RA 'descend, descend, monitor vertical speed.' TCASII indicated climb to miss conflict of traffic. Initiated a climb to 11000 ft, heading 020 degrees. Controller stated, 'you climbed back above traffic and you should be on 340 degree heading.' 'no, we were issued 020 degree heading.' no further problem. Landed las. Called las TRACON and spoke to the controller and asked him what the confusion was. Basically stated being a long day with 2 hours left to go. There was no problem and asked me if we were going to pursue this matter. I said no, just want to make sure everything is 'ok' -- no violations or instance filed. He informed, 'no, not unless you want to.' I said no. Then asked me if I would file a NASA report. I told him 'no, but if you would like me to, I would.' told me to have a nice day and not to worry about anything. Chain of events I believe were the expeditious descent asked by approach and a turn into traffic.

Title: HS25 FLC CHALLENGE L30 CTLR WHEN HDG CAUSES TCASII MANEUVER.
Narrative: LYNNS 1 ARR FROM PGS TRANSITION. ISSUED CLRNC TO DSND VIA STAR LAS. LEVEL 12000 FT LYNNS, TURNING R PER FMS TO MIROT TO CROSS AT 11000 FT. TFC WAS DEPICTED ON TCASII 700 FT LOW. CTLR ISSUED A DSCNT, 'EXPEDITE OUT OF 10000 FT FOR 8000 FT.' MOMENTS LATER, CTLR ISSUED US A TURN TO 020 DEGS INTO TFC WITH ALREADY AN EXPECTED DSCNT. BECAME A TCASII ALERT, FOLLOWED BY RA 'DSND, DSND, MONITOR VERT SPD.' TCASII INDICATED CLB TO MISS CONFLICT OF TFC. INITIATED A CLB TO 11000 FT, HDG 020 DEGS. CTLR STATED, 'YOU CLBED BACK ABOVE TFC AND YOU SHOULD BE ON 340 DEG HDG.' 'NO, WE WERE ISSUED 020 DEG HDG.' NO FURTHER PROB. LANDED LAS. CALLED LAS TRACON AND SPOKE TO THE CTLR AND ASKED HIM WHAT THE CONFUSION WAS. BASICALLY STATED BEING A LONG DAY WITH 2 HRS LEFT TO GO. THERE WAS NO PROB AND ASKED ME IF WE WERE GOING TO PURSUE THIS MATTER. I SAID NO, JUST WANT TO MAKE SURE EVERYTHING IS 'OK' -- NO VIOLATIONS OR INSTANCE FILED. HE INFORMED, 'NO, NOT UNLESS YOU WANT TO.' I SAID NO. THEN ASKED ME IF I WOULD FILE A NASA RPT. I TOLD HIM 'NO, BUT IF YOU WOULD LIKE ME TO, I WOULD.' TOLD ME TO HAVE A NICE DAY AND NOT TO WORRY ABOUT ANYTHING. CHAIN OF EVENTS I BELIEVE WERE THE EXPEDITIOUS DSCNT ASKED BY APCH AND A TURN INTO TFC.
