The directional shadow light was placed at focus + theme offset (only ~17-32 units), while the ortho shadow camera ran near=1/far=100. That left the focus near the front of a long frustum whose far end swung around as the look-at moved, so shadows appeared not to follow the view. Park the light at a fixed distance along its (preserved) direction and bracket near/far around that distance so the focus stays centered in the frustum depth.
