I don't know, maybe the video was up there so Record Company people and the band could see it and approve/disapprove, talk about changes they'd make. After all, if the band are on tour it's not like they could hit the editting suite and have a face to face meeting, and the internet is a good place for conference calls etc. Pretty sure us fans were never meant to find out it was up there.
I'm sure it will leak out eventually.
