Darth Maul. I think Lucas wouldn't do it to himself without some sort of explanation.
George Lucas' treatment of the Expanded Universe seems to be that he treats it the same way that the Expanded Universe treats Infinities. He doesn't consider it 'canon' to "his world," which he distinguishes as separate from the Expanded Universe, but he will "reference" stuff he likes into "his world" from the Expanded Universe in the same way that the Expanded Universe will "reference" stuff from Infinities "into continuity," e.g. "Resurrection."
I think Leland Chee or LucasFilm is going to have to address the concept of continuity again. I've defaulted back to the original explanations from SW Insider and the SW Encyclopedia until this is cleared up:

"'Gospel,' or canon as we refer to it, includes the screenplays, the films, the radio dramas and the novelizations. These works spin out of George Lucas' original stories, the rest are written by other writers."
and
"When it comes to absolute canon, the real story of Star Wars, you must turn to the films themselves—and only the films. Even novelizations are interpretations of the film, and while they are largely true to George Lucas' vision (he works quite closely with the novel authors), the method in which they are written does allow for some minor differences. The novelizations are written concurrently with the film's production, so variations in detail do creep in from time to time. Nonetheless, they should be regarded as very accurate depictions of the fictional Star Wars movies.
"The further one branches away from the movies, the more interpretation and speculation come into play. LucasBooks works diligently to keep the continuing Star Wars expanded universe cohesive and uniform, but stylistically, there is always room for variation. Not all artists draw Luke Skywalker the same way. Not all writers define the character in the same fashion. The particular attributes of individual media also come into play. A comic book interpretation of an event will likely have less dialogue or different pacing than a novel version. A video game has to take an interactive approach that favors gameplay. So too must card and roleplaying games ascribe certain characteristics to characters and events in order to make them playable.
"The analogy is that every piece of published Star Wars fiction is a window into the 'real' Star Wars universe. Some windows are a bit foggier than others. Some are decidedly abstract. But each contains a nugget of truth to them. Like the great Jedi Master Obi-Wan Kenobi said, 'many of the truths we cling to depend greatly on our point of view.'"
I've put it under spoiler tags because it's long and I didn't want to take up a lot of space, but it isn't a spoiler or anything. I think that TCW falls under this similar category since Lucas is overseeing it and pretty much all ideas are coming from him and if they aren't he's approving them.
