Yeah, it sounds like Lucas is desperately trying to justify his revisions, which is really dumb. I'm not a complete Star Wars nerd, but I have enjoyed the original trilogy and -parts- of the prequel trilogy. I've played a few of the games, but not all of them. So, coming from a casual Star Wars fan, it's always been my opinion that a) Han did in fact, shoot first and b) it was STILL self defense. Why? Well just watch the original scene. Greedo had a blaster pointed at Han. Han tried to reason with him, but Greedo wouldn't hear it. He then sounded like he was getting ready to pull the trigger, so Han, rather than waiting for the blaster pointed at his chest by the guy who hates him to actually go off at point blank range, shoots him. I doubt there are many courts that would convict Han on that sort of evidence.
