I have to assume that one of the bidders pulled his bids, as you can see one bidder has numerous bids - this appears to me that all of anothers bids were dropped or pulled by the other bidder - I have been screwed by a bidder bidding it way up and then at the last moment someone pulls all their bids and the item drops way down...
