Well that's the real trick, isn't it.
It's kind of a shame that Disney won't release the unedited version (they did release Education for Death, after all) - but the trick with any reel of film is whether it has the unedited version intact. I know of one unscrupulous seller that when asked if it was unedited, replied "yes," and when the buyer received it, found that it had been cropped, and the seller said he meant that "the scene hadn't been cut altogether." Not cool.
