The thing is, the post-'97 versions ('04 and '11) were never marketed as Special Edition or any specific version of the movies, so I can easily see a situation, where the people currently in charge of this new restoration aren't even aware of any of the subsequent changes and they think that by making a restoration of the 97SE, they are making a restoration of the "George Lucas approved director's cut" version, which they think is the same version seen on the '04 DVD and '11 BD.

Considering how many people would have to be involved. (possibly including George Lucas being informed) That all probably LOVE film, and very likely Star Wars...I think it's a little doubtful that NO ONE on the team would raise this issue.

edit: Hell they'd have to go actually physically get the negatives at Lucasfilms for scanning...someone at lucasfilms would raise the issue.
