Cuz the Moog intent of those is to move the UCA out laterally for more positive camber to compensate for a sagging or damaged subframe. We put the front one in as designed and put the arrow to the inside on the rearward one on each dr/pass side so that the front is moved outward as originally designed but we move the rear leg in which in effect moves the UBJ rearward (in a slight arc) for more positive caster.
