Memory lane's Autobid

[Rhotchkiss]

As most of you know, Memory Lane Auction has an "Auto Bid" feature. The way it works -- and I just learned this by reading "what is autobid": "if someone outbids you, the AutoBid acts as your agent and raises your bid to the next acceptable winning bid. "

So, if I autobid several increments up from the current bid, shouldn't I own each increment up to my Autobid limit? For example, if the increments are $10, and the card is currently at $100, and I put in an autobid of $170, shouldn't I own each position between $100 and $170? But this is not how it works. Instead, the guy who bids $110 gets that position (not my autobid) and then I get the $120 spot (because of my autobid). How is it fair that the AH can push me to the second to next increment when I have already, beforehand, said I would take the next increment. Shouldn't I have "dibs" in this case?

Is this normal/how other AH's do things? I do not think Heritage works that way (I think you get dibs).
