I'm not sure this is true and if it is, it's not smart.
Lets say we are willing to go up to 15m eur for a player. It will be silly to offer 15m right away and we should try with a lower offer first, hoping that it might be accepted. So, we offer 11m eur. If another team offers 12m, it would be too silly not to offer more just so we won't enter a bidding war, when we are already willing to go up to 15m eur for the player.
