Yeah, the last time I played I was lazy and set Squall's attack and Renzokuken to Auto, and once in a while I would get Lionheart. Maybe there are other statistical factors (Luck, etc.) involved?
Things like that might increase the probability somewhat, but nothing will ever guarantee that Squall uses it every time.
