I think it’s been determined the editing was done to remove the original theatrical footage from the doc and replace it with the current cuts? I believe that’s the case. Everything else seems to be exactly the same.
I skimmed it the other night and the original crawl, the Alderaan and Death Star explosions, and Han running into the stormtrooper hallway were the same as they were in the OUT. Not sure why some footage was changed and some wasn’t, because I remember hearing about the footage being changed to SE too.
