I think he is saying (and it is hard to know if that really is his point) that he feels that when Adywan finishes his revisited trilogy, that will be his definitive version of the OT.

That's how I understood it as well. And the same goes for me--once Adywan is done ESB:R, that will be my definitive version. The same goes for ROTJ:R and ANH:R:HD. I can't speak for the prequel trilogy yet, but his will probably replace the originals unless he isn't able to finish them in the end.
