Why does swinging your head opposite of the spin prevents you from passing out?

So there’s this scene in Interstellar where their ship explodes and it makes the ship spin. The girl doesn’t move her head against the spin and she passes out while the experienced guy held his head the opposite of the spin and didn’t pass out. Why’s that? Is it something to do with blood rushing out of the head because of the spinning?

For what it’s worth, the movie (as described here) isn’t accurate. The premise is that blood flows outwards from the spin, so blood to your feet causes you to pass out, but blood to your head doesn’t. Your head isn’t designed for that, though, and you’ll actually pass out sooner (red out, due to blood going to eyes). You can train yourself to survive high positive pressure, but not negative pressure
