But that’s the ‘real’ version of what happened. It’s kind of a key resolution to that plot element. Though if you delete it, leaving only the two less accurate recollections, I suppose that would add an interesting amount of additional ambiguity.
I have seen a tweak to it here (I don’t recall who by, sorry) where it was adjusted to have Luke explicitly turn his saber off before Ben struck at him, making it clearer that Luke wasn’t going to attack him, which might be the sort of thing you’re looking for.
