It does “feel” weird, I bug reported a similar thing myself, but just hadn’t thought it through fully.

Easy way to see what happens:

Bidder A places bid for 10.000 – bid is set to 1,000 (min bid)

Bidder B places bid for 9,000 – bid jumps to 9,250 (bidder A winning)

Bidder C places bid for 10,000 – bid jumps to 9,500 (bidder C), then 9,750 (bidder A), then 10,000 (bidder C)

That is the breakdown for that final bidding war, but all you would see would be a jump from 9,250 for bidder A to 10k for bidder C. Not seeing the back and forth bidding war that is happening all the way up the chain is what is confusing. In the example above the jump from 1k to 9,250 had tons of back and forth bids that aren’t shown either.

It has nothing to do with who bid first, simply whose turn it is to bid when that max bid number hits.
