No, because the pre-spinning (torque applied to rotor) part happens on the ground with the rotor blades set to low/no pitch. The rotor then starts freewheeling (no torque applied or transferred from the rotor) and the blades' pitch angle is increased, which slows the rotor down, but momentarily creates enough lift to lift the autogyro into the air, where it immediately transitions to forward flight.
