I think you've hit it. I always adjust cones with the wheel loose. So, one side is tight, the other side is being tightened. And, both the cone and lock nut move slightly when locking down, hopefully moving to a place generally preserving the cone's position.
By putting the axle in the vise and holding the cone wrench fixed, then one is pushing the cone to one side.
