The command was given to both of them, no one could deny that fact. However, Minx hadn't moved to obey it due to the two-tails prior lessons on how to evade pursuers in the case anyone ever learned of her 'Jinchūriki' status. It was always very clear with her that in its mind the best way to 'win' against or rather 'escape' a group was to use the group against itself, figure out which members had the least teamwork ability. She'd never worked with Celestia before and guessed that fact probably showed. Having seen the other girl move in first, Minx would not be giving the teacher an opportunity to duck them and send them into each other.
Observing she watched the jutsu utilized, realized the complete look around at each of them, a check of somekind before the other girl whistled. There had to be some reason for what she'd seen, perhaps Celestia was just self conscious, but maybe it had some sort of friendly fire. Nodding to herself Minx made a note that in the future she'd always make sure not to get closer to Celestia than an enemy was, encase it was that sort of deal. Better safe than sorry as Two-tails would say. "Agreed, you did a great job knocking him out. I'm glad I stayed out of your way, and sadly I doubt I'm psychically capable of carrying him." Yeah, Taijutsu was her best skill but hers wasn't exactly built on how much strength she could hit someone with, after-all everything she knew in the world so far had mostly been taught by a cat.
