The purpose of a two system (dual) rudder is the same as the ailerons
(inboard and outboard).  During slow speeds (takeoffs and landings),
both systems (upper/lower rudders) work together for effective
control, while at higher speeds (cruise) the need for large control
surface movement is lessened.
