I didn't know that, but I don't use Twitter. I just saw all the articles that quoted his earlier statement. This tweet is interesting though, as he says "happened long before I came to the Story Group" as he was part of the Story Group since its beginning in 2014, and he was the head of the pre-2014 "Story Group" for many years up until 2014.No, that was Leland's personal justification for the wipe, not the reason why LucasFilm did it.

Perhaps. Perhaps not. The Story Group was formed in 2014, just after the original script for episode 7 was thrown out(Michael Arndt was let go or quit, and JJ was asked to write a new script. He even visited Lucas at his home for a "blessing")The stated purpose of the Story Group was to go through the EU(especially the post-rotj eu), and pick/choose what to keep, and what not to. They later decided to scrap the whole thing except TCW and the films. This was 2 years after Lucas left, and a couple of months after "throwing out his story" as he later stated.And despite what some seem to insist, it wasn't Disney that ended the EU, it the Lucas the second he decided to start making the ST, which was *before* selling the company. Do people really think LF would have continued publishing post RotJ EU material while also telling an entirely different version of events in the cinema *and* also publishing the usual requisite of narrative tie-in media?
Did Dark Horse keep going with their old Clone Wars stories after the animated series came out? Hell no.
Back to the Chewbacca thing: In 1999, the Lucasfilm story people were putting together the New Jedi Order series, and wanted to have a dramatic death of a main character in the first book. They wanted to kill Luke. Lucas said "Absolutely not." And told them which characters were off limits. So they chose Chewbacca.
Also, prior to 1999, Lucas Licensing/eu authors were forbidden from writing in the Clone Wars/Prequel era. Why? Because Lucas had plans to make a Prequel trilogy. They were only allowed to do "old Republic" stories if they went 3-4,000 years back so as not to interfere with future films.
The RotJ Legends timeline ended with Luke being about 65 years old, the same age as Mark Hamill.
So when the Prequels were made, Lucas had a blank slate and not interfere with any books/comics, etc, and when the Sequels were being made, there was likewise, a blank slate.
