This strikes me as both pedantic and wrong. I think it's covered by L12C1a & L12C1f. I usually tell players that they are allowed to change the call if it was influenced by the misinformation. That way anyone with doubts can ask me after the hand is over to look at the actions taken, but I'm not going to look at the hand and offer an opinion during the auction period. In practice, I don't think I've known of a situation when someone wanted to change their call in these circumstances for a reason other than that it was influenced by the misinformation, but I have no doubt that such a case will shortly occur at a certain North London bridge club.
