It is intended as the skill type only checks whether both leader and ally are one of the three cards, it doesn't check for duplicates.

I haven't seen the analysis video, perhaps they changed the teamskill condition after initial complaints, but right now you can use (eg) Mai as both leader/ally for the teamskill to work.
