From the report's precis:
The vertical separation between the two aircraft was influenced by chance alone as the flight crew of VGP and the pilot of 7456 were not aware of the altitude of the opposing aircraft
The pilot of 7456 was not even aware there WAS an opposing aircraft, let alone what altitude it was. It didn't matter to old mate in the Jab what type the opposing aircraft was. He hadn't heard any broadcasts, and didn't see the A320 until after they had passed. If not, he'd have landed at EVD none the wiser. VGP advised the other inbound 737 on the CTAF of the traffic heading their way almost immediately after it happened. The report doesn't say whether there was any conflict resolution between them and the Jab, or was there deathly silence there too? Did old mate Jab pipe up and work it out with the next jet, or had he missed that call too?
