Just took a quick look at the ebay page. He is not claiming that it is a retail laserdisc - he says it is one of the actual discs that was used to play the film at Disneyland. It is therefore possible that it is legitimate, though I don't have any idea if Disney actually used laserdiscs to play the films. I also noted that he has been on Ebay for a long, long time, and has 100% feedback, which does give him some credibility. How he managed to get an official copy of the laserdisc is anybody's guess though.
