Narrative:
In holding pattern at 5000 ft, conflict aircraft also in holding at 4000 ft, requested clearance to divert to ewr. Conflict aircraft was pointed out by approach. We responded that we had the aircraft visually. Clearance was given to descend to 4000 ft maintain visual separation fly heading 220 degrees. Conflict aircraft was at our 1 O'clock position. We turned to heading 270 degrees in our descent to maintain visual separation. A clearance from approach to turn as necessary to maintain visual separation would have made the situation clrer in my mind. Supplemental information from acn 198792: TCASII gave TA and short RA asking for descent. Heavy cockpit load at time with desire to expedite divert added to confusion.

Title: CLOSE PROX ACR MLG LEAVING AHD VISUAL AND ACR MLG IN AHD.
Narrative: IN HOLDING PATTERN AT 5000 FT, CONFLICT ACFT ALSO IN HOLDING AT 4000 FT, REQUESTED CLRNC TO DIVERT TO EWR. CONFLICT ACFT WAS POINTED OUT BY APCH. WE RESPONDED THAT WE HAD THE ACFT VISUALLY. CLRNC WAS GIVEN TO DSND TO 4000 FT MAINTAIN VISUAL SEPARATION FLY HDG 220 DEGS. CONFLICT ACFT WAS AT OUR 1 O'CLOCK POS. WE TURNED TO HDG 270 DEGS IN OUR DSCNT TO MAINTAIN VISUAL SEPARATION. A CLRNC FROM APCH TO TURN AS NECESSARY TO MAINTAIN VISUAL SEPARATION WOULD HAVE MADE THE SITUATION CLRER IN MY MIND. SUPPLEMENTAL INFO FROM ACN 198792: TCASII GAVE TA AND SHORT RA ASKING FOR DSCNT. HVY COCKPIT LOAD AT TIME WITH DESIRE TO EXPEDITE DIVERT ADDED TO CONFUSION.
