Since the last time you saw it was before it was out on video, I am guessing you are just remembering it differently than it was. Seriously, I've seen a million examples of this. That's my take on it anyway. You may have seen the film a billion times, but you probably only saw it a few times before it was on video, and that was 30 years ago. Since, I was born after the film was already on video, I can't offer any confirmation or denial here, but then again, if you can find someone old enough to have seen the film in its original runs I doubt they would have noticed such an obscure detail in the first place and actually remember it even if they had.
