Narrative:

I was working the departure east position at mco. Air carrier X was on a 330 degree heading level at 9000 ft. The aircraft was instructed to join V267 from that heading. I notice air carrier Y on an intercept heading, descending out of 10000 ft. I heard the controller working the final M position issue traffic and request air carrier Y to maintain 'visual separation.' I took no action for fear of making opposite instructions. I did not think the aircraft came less than minimum separation (1000 ft and 3 mi). The controller working final M reported the situation because air carrier Y had TCASII and the controller thought the air carrier Y pilot would report it. The air carrier Y aircraft was delivered to the final M position by the arrival left position at an altitude that would put air carrier Y in the departure east airspace without a pointout. I did not observe the conflict until the collision alarm sounded.

Narrative: I WAS WORKING THE DEP E POS AT MCO. ACR X WAS ON A 330 DEG HDG LEVEL AT 9000 FT. THE ACFT WAS INSTRUCTED TO JOIN V267 FROM THAT HDG. I NOTICE ACR Y ON AN INTERCEPT HDG, DSNDING OUT OF 10000 FT. I HEARD THE CTLR WORKING THE FINAL M POS ISSUE TFC AND REQUEST ACR Y TO MAINTAIN 'VISUAL SEPARATION.' I TOOK NO ACTION FOR FEAR OF MAKING OPPOSITE INSTRUCTIONS. I DID NOT THINK THE ACFT CAME LESS THAN MINIMUM SEPARATION (1000 FT AND 3 MI). THE CTLR WORKING FINAL M RPTED THE SIT BECAUSE ACR Y HAD TCASII AND THE CTLR THOUGHT THE ACR Y PLT WOULD RPT IT. THE ACR Y ACFT WAS DELIVERED TO THE FINAL M POS BY THE ARR L POS AT AN ALT THAT WOULD PUT ACR Y IN THE DEP E AIRSPACE WITHOUT A POINTOUT. I DID NOT OBSERVE THE CONFLICT UNTIL THE COLLISION ALARM SOUNDED.
