Yeah, and he's made it his "director's trademark" since THX-1138 was his first film (the theatrical one (
http://imdb.com/title/tt0066434/) was based on a student film
http://imdb.com/title/tt0062331/) he made earlier). So references to it have appeared in plenty of his movies (Star Wars and Empire Strikes Back, and as you saw TPM as well, though I hadn't seen that one before).
Supposedly it's in all his movies. Other in jokes like this are done by other directors all the time.
So if you are a Lucas fan and you want to use that as your forum name, good luck. I'm sure it's well used!
