(Speculation mode on)
What if the 5.1 mixes for OBC and Meddle were done and the original press release was correct and by some strange decision they didn't make the final cut and were shelved at the very last minute?
This will partially explain why we have a new stereo for OBC, that maybe was liked by everyone.
If Mademoiselle Nobs was left out of Pompeii, maybe same election was made with the 5.1s.
If this crazy idea is true, there might be hopes for the surrounds to be added back to the box or released in the future. Ok, I guess the boxes should be in production already with no time for changes, but one can hope, can't I?

Your speculation mode is registering at '11'. If you could bring it down to around a '7' (or even better a '5') that would be great.
(Translation: I don't think 5.1 mixes of either album were ever prepared. Some language just got screwed up between the production and marketing department in that premature webstore listing, which happens.)
