I took this flight about 6 weeks ago DXB-LCA. Only the LCA passengers disembark, those going on to MLA stay on the aircraft. When disembarking, the crew check your boarding pass to ensure that you are supposed to be getting off at LCA and there is a headcount as you proceed down the aerobridge.

The aircraft sits on the ground for just under 1.5hrs and there is no crew changeover, so it's quite a fast onward turn.
