Your only bid/snipe was placed as $801.03 - AS doesn't bid up the item as you are suggesting. Instead it just places one bid at your max and relies on AS's proxy bidding system to sort things out!
1***i had two bids, one at $750 and one at $800. I guess s/he had second thoughts and upped their bid by bidding again.
1***i is a zero feedback bidder so must have been somewhat annoyed when your bid arrived just at the end!!!
