DaveReid: I would agree with that date. The video seems to show G-OOBN on the fuselage of the arriving B757 and that was indeed the aircraft flying BY7534 that day (arriving around 10:20 ish). Regardless of all the shock horror stuff, the pilot didn't reverse down the runway; he backed the aircraft up across the width of the runway, just to get the extra 10 or 20 metres needed to make that taxiway turn. Exactly as the thread title suggests; a 3 point turn.
