It has to do with the perception that Lucas had taken the storyline - which according to the stated theory was supposed to have gone on for four more films/episodes following TESB - and “compressed” it into a single film, ROTJ. In light of that perception, I think it’s relevant to bring up how much is revealed in the second film (TESB) and wonder how this really coheres with a notional six-part continuous story (SW + TESB + four more films), rather than a trilogy of trilogies with twenty some years between each trilogy.
Unless I’m wrong, that theory is false. Are you speaking of what Gary Kurtz said some years ago? He was confused and was talking of several ideas for the Star Wars franchise at the same time; the planned storyline Kurtz mentioned was never materialized or conceived in any way. As far as I know, Lucas first conceived Star Wars as a standalone movie, then as The Adventures of Luke Skywalker (with film or book sequels of SW) or as a franchise where every director could have complete freedom to do whatever movie they wanted, then (before February to April 1978) as The Adventures of Luke Skywalker with TESB being Episode or Chapter II and with unlimited sequels, then as a trilogy of trilogies with SW and TESB being Episodes IV and V, then as two trilogies (the Star Wars Trilogy and an unmade prequel trilogy), then as a hexalogy Saga. Lucas, Kurtz or anyone else never thought of a hexalogy with SW and TESB being the first two movies. The closest idea comes from the period between May 1977 and February 1978, where the Star Wars franchise was The Adventures of Luke Skywalker but there was no planned chronology or storyline at all, no fixed number of sequels.
