It was Ruben Martinez and not a faceless or nameless backroom member. More the goalkeeping coach who can be seen every week.
He was also heavily provoked and the fact that none of the Forest backroom lot were sent to the stands was a disgrace.
Because it is against the rules agreed between all the clubs. Whether you are in breach of FFP or not I have no idea, just hope if its found that you are (or any club) punishment is handed out accordingly.
