I don’t recall Luke choking anyone in ROTJ
I thought he was using a Jedi mind trick there.
I agree with Warb. We know what it looks like if someone is choking and that wasn’t what happened in that scene. I have always read the scene as Luke convincing the GGs to go back to their posts and sleep, their hands on their chests in a restrained or passive position.
They seem to be pushed back, not just walking back, so it’s definitely more than just a mind trick.
