This comes from a weak upper back, eyes moving down during a pull, trying to leg press a deadlift, starting with hips too high, starting with feet not under the bar, and several other common deadlift form issues.
If the leverages are a hair off the body will make corrections to protect itself and maximize strength, and they won't look pretty.
That's why a natural feel - a powerful feel - is what I aim for above all else when pulling. I don't form lock myself, but rather set my hips until I feel like I am in a position to rip something off the ground.
A good natural leverage feel, along with leading with the head and locking with the hips will help the body function as intended.
