Just in case anyone wants to believe anything written in those Archive books:
When the Jabba scene was cut, the Greedo scene did not make sense. It was shown with Greedo speaking an alien language without subtitles in 1977, so it looked like Han just shot in cold blood. Subtitles were added for the 1983 VHS release to clarify Greedo intended to kill Han.
Seems like that tweet is gone.
