Perry strikes me as the type who doesn't believe in lowering his speed and offense for inferior partners, ie, women, children, and even his fucking girlfriend.
Anyone who's spent at least a moderate amount of time training knows that you spar at your very lightest when you're partnered up with a girl. Typically you let them mount some offence instead of bombarding them qith pressure. He wasn't throwing bombs but he was keen to put his alpha stamp on her.
Gotta win every round in sparring, hey Perry? Don't let your girlfriend's chance of a good time get in the way of that.
