Well, for me it means that it shows that a player is not going to stop bidding after a few rounds and also that a player really wants the player from the transfer market (what you said). I've experienced that if a player is bidding against another player who is bidding right after the round started, the auction will have dozens of rounds. I didn't experience that when players kept bidding at the last second, those auctions often end after 10 rounds, atleast that's what I've seen.
