Not sure. But if that was the issue, I would hope and expect that there would have been decisions along the lines of, "We are limited by the technology, so Luke's dialog really needs to be pretty sparing. So let's make sure it is really tight so he can say meaningful stuff in just a few words." Instead, it was just a mess of gobbledegook. Like I said, it was just meaningless platitudes using Star Wars-y language. For the most part, same with Asoka.
