You can't go in and overrule your partner(s) but you should offer information in this situation so that it still can be corrected. Talking about it after is good for future reference but doesn't help anything going forward - and it reinforces a rule misconception with those teams that may need to be dealt with down the road. That's a secondary concern but still worth mentioning.
