because all 3 bids were placed by the one bidder, and as a buyer cannot ''outbid'' herself, it will stay at the start price until another bidder places a bid.
lets presume the current bidder has bid $110, $120 and $130
a new bidder comes along and bids $115, it will jump to $120 to bidder #1.. and so on
