The phrase "Possible Pilot Deviation" that you heard is meant for these purposes. It's said to remind the pilot that this was not normal and will be looked into so they will need to remember the details, otherwise they would likely forget all about it before the time they get questioned. They probably wouldn't forget this instance as getting stuck at the airport ought to be pretty memorable, but it is also said for less obvious issues where FAA rules may not have been followed.
