If North is given the opportunity to change their final pass, are comments made by South after the correction of wrong explanation AI?
It is South who first bid after the MI and would have acted differently, why is the bidding not rolled back to South?
This is my reason:
When a player is misinformed it is akin to improper deception. The damage being that he was influenced to not do what he would have done (distinct from what he might have) or to do what he would not have done. The remedy of do over is an attempt to fight it out at the table on as level as practical playing field.
Practically, going back more than one turn disturbs** the playing field beyond repair. In many cases MI is immaterial to one or both players and the TD can inquire both before rolling back to that turn as to what the turns would have been for the purpose of ascertaining damage (should the do over not save the comparison) while minimizing contamination.
** the information from rolling back two turns puts the player with the earlier turn in the position of knowing information from partner that he would not have without the remedy. This imbalance of turns destroys the justice that comes from the practice of alternating turns. Thus, rolling back more than one turn is irreparable.
