I have read through a number of previous threads and I think I have this right, I just want to get a quick confirmation. Turn 1. A YuanYuan in order group one drops using his impetuous order inside of ZoC of a Mutt. The Mutt jams successfully, YuanYuan fails his BTS. The YuanYuan still has its irregular order generated off board that he placed next to the model at the time of deployment. It can either spend that irregular order to do skills, or, with a command token, that order can be converted to regular for other members of group one to use. Is that correct?
You cannot convert Irregular Orders to Regular after the Tactical Phase of your turn. Otherwise, the Irregular order is unaffected. The model cannot receive orders from the Order Pool, and Irregular order are no part of it.
You're presumably thinking of moving troopers between Combat Groups. There's no such restriction for turning Irregular Orders into Regular ones. Whcih can be really handy when your Irregular Warband get themselves slaughtered in the Impetuous Phase. :-) In the same Turn it should be OK, but for subsequent Turns, previous discussions came to the conclusion that the Irregular Order is 'stuck' with that trooper due to the second Effects bullet for Isolated: If, at the start of his following Active Turns, the trooper is still Isolated, then he is considered to be Irregular and it does not add his Order to that Turn's Order Pool. With it's doubling of becoming Irregular AND not adding to the Order Pool.
