It won't be obvious that everyone will go for 1 point even if it would ensure going to the next round. Getting the 500 point bonus for highest bid will be valuable at the later stages of the game when there's less players and everyone has less points left.
Anyways, i also think that it's not a very good rule and just lenghtens the game unnecessarily.
