Allow me to turn the question back to you? Why do we have two types of grabs for Morphs depending on how we pick it up? One which attaches the Morph to the hand, another which attaches the halo to the hand and leaves the Morph following along well below the hand
Both types behave similarly: they do not move the morph upon grabbing it. You have to move the hand to move the morph, which makes sense to me.
