If you are referring to the movement of the blades about the coning hinges on the R22, or what some might mistakenly call the flap hinges, they do not move with changes in cyclic, only with changes in coning, such as might happen with a change in load.
The two blades will always move together as a pair, about the teeter hinge.
With forward stick, the cyclic pitch, reaches a maximum roughly 90 degrees before the blade reaches the aft position in the Rotorway, and about 72 degrees before, on the R22(because it has a delta-3 angle which affects the phase angle).
In both ships, the blade reaches max upward displacement over the tail, assuming forward cyclic.
The rear blade does not push the opposite blade down. The pitch is reduced on the forward blade which changes the balance of lift vs centrifugal force and causes the blade to move down in front by the same amount that the other blade moves up.
