Default cyclic boundaries not identical

Smed is on a distinguished road
I have two plates which use the cyclic boundary condition in OpenFOAM 2.0.1, and at any given timestep, the solution on each of these boundaries is not identical. I'm wondering why this is the case.

Does the cyclic BC utilize ghost cells which could cause this to happen? Could it be because these plates are not parallel?
