Maybe the more complex mode would enable throttle "blipping" for downshifts, ala BMW...I don't see why the ECU couldn't down shift. It knows the speed of the output shaft via the rear wheel speed sensor, the speed of the crank, the current gear ratio and the next lower ratio so it could calculate matching rpm and has control of the throttle to make that rpm happen.
