Narrative:
While working final approach radar to jfk, VOR 13L approach, WX is VFR, traffic light, complexity light. Cleared light transport for VOR 13L approach, cross asalt at 3000 ft (asalt is VOR 13L approach fix). I received a landline call from the lga empyr sector for a pointout on an air carrier X large transport that was presently southeast descending out of 3400 ft. The controller requested that air carrier X 'turn northeast, reference your large transport.' I approved the pointout. I thought that the air carrier X would make a right turn to the northeast. The large transport made a left turn. The air carrier X large transport was now almost on top of the light transport at the same altitude. Both aircraft are descending. Local controller, who by this point was working the light transport, advised that light transport had the large transport in sight, but needed a right turn to avoid the large transport. This event was the result of poor communication and coordination. The lga empyr controller should have specified that the large transport would make a left turn. I should have asked which direction the large transport would turn.

Title: CONFLICT BTWN 2 ACR ACFT MAKING VISUAL APCHS CAUSED BY MISCOORD OF ATC CTLRS.
Narrative: WHILE WORKING FINAL APCH RADAR TO JFK, VOR 13L APCH, WX IS VFR, TFC LIGHT, COMPLEXITY LIGHT. CLRED LTT FOR VOR 13L APCH, CROSS ASALT AT 3000 FT (ASALT IS VOR 13L APCH FIX). I RECEIVED A LANDLINE CALL FROM THE LGA EMPYR SECTOR FOR A POINTOUT ON AN ACR X LGT THAT WAS PRESENTLY SE DSNDING OUT OF 3400 FT. THE CTLR REQUESTED THAT ACR X 'TURN NE, REF YOUR LGT.' I APPROVED THE POINTOUT. I THOUGHT THAT THE ACR X WOULD MAKE A R TURN TO THE NE. THE LGT MADE A L TURN. THE ACR X LGT WAS NOW ALMOST ON TOP OF THE LTT AT THE SAME ALT. BOTH ACFT ARE DSNDING. LCL CTLR, WHO BY THIS POINT WAS WORKING THE LTT, ADVISED THAT LTT HAD THE LGT IN SIGHT, BUT NEEDED A R TURN TO AVOID THE LGT. THIS EVENT WAS THE RESULT OF POOR COM AND COORD. THE LGA EMPYR CTLR SHOULD HAVE SPECIFIED THAT THE LGT WOULD MAKE A L TURN. I SHOULD HAVE ASKED WHICH DIRECTION THE LGT WOULD TURN.
