Funny, I think the Luke stuff is really from the original shoot but I think the Vader stuff is all cobbled together from outtakes. Perhaps that corridor shot is from 1983 but I don't recognize that corridor, and the moment of him entering the elevator is probably from 1983. Of course it's an elevator in the Emperor's throne room, where the telepathic communication scene was supposed to take place. So why is he walking out of there? It's the meditation chamber that I think is out of place and is just an ESB outtake. They would not have re-built that set for one shot in the movie. And the script called for this scene to take place in the Emperor's throne room. That's the footage we're not seeing here.
So what I think we're ending up with is a recreation of a deleted scene.

I agree the Vader stuff looks a bit cobbled together, but ROTJ was never as visually fluid as the first two movies to
begin with. It might have always been their intention to simply reuse leftover footage.
Besides, I don't see why there couldn't have been a duplicate meditation chamber located on the second Death Star. Heck, Vader probably had one on the FIRST Death Star too, and we just never saw it.
