Absolutely correct...as lift is transfered from the main rotor to the wings, power is transfered away from the main rotor transmission, in effect keeping the rotor tip speed (where they stall) below RBS. Like all hybrid systems (tilt rotor for example) the transition period is most critical. Maneuvering speed is everything.
I don't know where they are in the test profile, but VTDP seems promising
