I don't know if anyone else has noticed this, but the '97 mix (to my ear) sounds like a different recording than EITHER of the two ADR jobs. At least part of the ADR is different in the SE (presumably carried over from the 70mm?). It is definitely more similar to the stereo ADR than the mono ADR, however.
But yes, if they use the '93 audio, then their claim that this is the original version of SW as seen in '77 is false. Of course, their claim in '95 that SW was presented in the original version was also false (it contained the "ANH" crawl).
If they made false claims before, I don't see why they can't do it again.
