That is incorrect. All material in the expanded universe was created with Lucas' vision in mind. They are themselves, extensions of the 6 films, which is why the Holocron system labeled them G-canon - the highest order of the canon within the continuity. You are correct in pointing out that Legends and Canon are two separate entities, but that does not mean that legends are handled any differently now. There simply is no proof for that. And may I remind you how expanded universe was viewed, by the people responsible for that handling it?
"In a nutshell, anything created by the author would be C-level. Anything in the the novels created by George Lucas (whether it comes from unpublished early script versions, unpublished author interviews with George, or George's revisions to the novelization manuscript) would be G-level unless contradicted by the films."

GL is certainly not bound by the EU, though he's certainly open to using things created in it (Aayla Secura and the Coruscant name, for example). On the other hand, the quote you provide makes it sound like the EU is separate from George's vision of the Star Wars universe. It is not. The EU must follow certain tenets set by George through the films and other guidelines that he provides outside of the films."

There is no reason to deny this other than fanboyism for Yoda, and by extension, Sheev. George is the ultimate authority regarding everything in Star Wars Legends. So when a statement or feat regarding some ambiguous or undefined aspect of a work is inconsistent, the Word of God comes in as the ultimate authority. Such edicts can even go against events as were broadcast, due to someone making a mistake - in this case - it's the level of power demonstrated by PT Jedi in the Clone Wars Micro Series.
"The way George explained it to me going in was that THE CLONE WARS micro-series was really an experiment to see what kind of audience there was for Star Wars in an animated form.[...]So when we into doing this, I think that, now that George is done with the prequels, he wanted to reestablish the rules a little bit more, like "Mace Windu can't take out hundreds of battle droids by himself, otherwise the arena on Geonosis would've been a wipeout"
- Dave Filoni on Lucas' guidlines
It is very simple, Lucas dictates the rules, meaning those awesome feats are out the question. So instead, we can look to Yoda's other showings, which can be found in the movies, the Dark Rendevouz novel or a sourcebook explicitly stating Yoda's limitations and how he declines with age.
The microseries wasn't canon and no one has claimed otherwise.
Again, do you want a sticker?
The microseries, like lots of other things that Lucas doesn't give a shit about, is part of the Legends brand.
Well he very clearly did give a shit about it Gideon. Do I need to post that quote again? This is not the first time he get's involved with things outside the movies either. For example, the Force unleashed video game was created with Lucas' council. You can find a lengthy description of that process in the blurb of the Graphic Novel itself:
