Great point, agree. Letting him solidify a free swing up to impact for now to get a measure of consistent effortless pop despite a slightly errant toss (the reason he moves his foot to realign his platform to strike with a free swing). A few weeks and that front foot will be brought into focus with a more consistent toss.
serve looks great! you should tell him to stop moving his front foot before contact. that might increase his consistency.
