Hopefully this does not open me up for chastisement or ridicule but I will respond to your ??
Assume that heavy gusting perturbs the disc. When the blades flap up or down in relation to the commanded disc attitude there will be pitch flap coupling and the blades should return to the original tip path.
Now we stretch that point a bit further. If it is possible to perturb or move the fuselage in relation to the blades with out disturbing the disc, the blades, due to GYROSCOPIC RIGIDITY, will maintain their position. However the swash plate, which is fixed by the servos will move in relation to the rigid blade disc forcing the pitch links upward or downward depending upon the relative movement between the blades and the fixed pitch links and some pitch change will be input.
I am now open to criticism.
