So when you have Physick as the first line, it casts on your highlighted target, then drops the highlight, leaving Embrace to cast on your selected target. When you have Embrace as the first line, it casts Embrace on the highlighted target, but doesn't drop the highlight, so Physick casts on the still highlighted target.
