If the asking bid is $5 and I bid $50, the opening bid will show as $5
If you then bid $10, the high bid will show as $11 to me.
If you then bid $12 the high bid will show as $12 to me.
If you then go nuts and bid $50, the high bid will show as $50 to me since I bid first.
This is making you crazy so you bid $100 and at last the high bid is to you-- at $51.
Provided no one else bids, you will win at $51.
But is Bidder r***b comes along and bids $75, you will still be winning -- at $76.
Does that help?
