Scott hit the nail on the head. The auctioneer CAN reopen bidding per the terms, but CHOSE not to. I see no point to doing so in this particular case, and in those occasions (twice ever) where I have heard of an auctioneer exercising such right are both extremely rare and usually something egregiously caused by the fault of the auctioneer. I think it's important to note that such a term of an auction is listed more so to allow the auctioneer an extra right, but not necessarily there to allow you as a bidder to request its use.
Personally, I think it's in bad taste to discredit the auction company because of something beyond their control. I can't imagine any auction company, anywhere, reopening bidding after the auction ended based on your request.
