It could have also been that they didn't have ample access to the source material for all the tracks, or that they didn't want to invest the money. Seemed they were being pretty careful about copyright during the Anthology days. Another thing to consider is that the PB tracks were getting a lot more work in the remastering department than tracks from other albums.
