It's because the cards you get don't depend on the animation you get, it's the animation that depends on the cards. As soon as you summon, the random generator decides what you get. If you summoned at least one SSR, you have a chance to see one of those animations that "guarantee" an SSR, but the animation always gets chosen afterwards.
