I was never bothered by the hatch shot myself. I always assumed it was a touch of backtracking when they showed Luke's POV. I've read a lot of books like that, so that's what I always thought.
There's also a bigger case of that right at the start. We see the probe crash, and the droid float away, then we see the probe crashing from Luke's POV. I thought about editing it all together, but it's definitely a creative decision that shouldn't be messed with. The hatch seems more like it's done for shot length than anything else, so it might be fair game.
