@Rachin, what I am trying to say is that by straining himself, he can warp things faster. He strained himself to the point of collapsing with blood gushing from his eye, and he managed to finish the technique faster than Obito's perception. The swirls were there, he just finished off the technique before it was noticed. He did do it. It happened. So that's one of Kakashi's feats.
