The one in the middle is directly on top of him. The other two flank it and are meant to catch him if he decides to shift his position to dodge the middle one. If he wants to dodge the three attacks then he will have to shift his position entirely and get out of the way of the Celestials.
But he doesn't plan to do that. He didn't shift during the time the Celestials were approaching him and he won't shift now that they are right on top of him. So he must pay the price for his arrogance.
The three phantom blades came close enough to strike him. He didn't dodge so the one in the middle was about to make contact with him. It chopped down aiming to split him in half. He finally paid attention at the last moment. One of his arms swung a claymore against the middle blade.
