I think the thing is, in the originals, he only talked "backwards" when it happened to sound natural. For years, I was never able to quite pin down what was so special about the way Yoda talked because it just flowed so naturally and sounded so cool. But with Lucas writing the dialogue, it seems the only thing he thinks is, "Wow. People like the way Yoda talks, so I'd better do it all the time." So every line of his was reversed. I only first started to notice this in Attack of the Clones, when I heard classics like, "To the forward command center, take me!" I stopped and thought, "Whoah. What in the heck was that?" And it only got worse in Sith. "That misread the prophecy could have been." I know I've said it before, but it actually took me a few seconds to decipher what was being said. That's when I finally realized that the whole thing was just screwed up.
