Sounds like we're in agreeance, AnFI, though my aim is more to make sure I understand the balance of forces and moments clearly than to prove someone else wrong!
With a semi-rigid or rigid head, as you say, the leftward inclination of the rotor disc to provide the side force will also be associated with an anticlockwise torque applied to the mast head (as seen from the rear of the aircraft), which I think would increase the leftward roll angle a bit. Maybe!
