I don't think they actually know what's in the package until a consumer buys one, watches it, is surprised, and then angrily returns it.
This is not the first time Columbia TriStar (Sony Pictures Entertainment) screwed up on a musical release. Their very first local VHS/VCD release of the NEW
Jesus Christ Superstar (2001) had the new jacket and artwork, but actually contained the
1973 version of the film.
I was the angry consumer who brought that one to their attention.
