There's enough play in the bushings to work with, and the locating points allow for the camber arm to move a good bit without binding anything. You have to realize that lowering the car changes the geometry anyway so the 'twist' you suggest doesn't apply. It doesn't hurt to have a pair but usually adjusting them any substantial amount greatly effects the car's handling.
