That's weird. My first thought was that actually supports the kooky Marcia Lucas theory, (since she'd be entitled to half of "STAR WARS-1977" but not "Star Wars Episode IV A NEW HOPE -1997".) But maybe there actually is something to that? It sounds similar to what happened with Blade Runner, in that from 1992 to 2006-ish, Jerry Perenchio's contention was that Warner could release the '92 version (for which they worked out a deal for its theatrical release) but not any previous or future versions without them undergoing a separate deal.
