Not to pile on, but I think that's the key issue. His hips should start lower, and he raises his hips even more before the pull. He's out of position after the first pull, and everything cascades from there.
I'd focus on starting hips down, chest up, and focus chest up for the first pull.
But I'm far from an expert, so when a real expert (like Greg) weighs in here, listen to him, not me.
