Sliding mesh interface - problem with velocities

I have this relative/absolute velocity problem, I think. When in the stationary domain, velocity vectors near the interface point from left to right. While on the other side of interface, in the moving domain, they seem to be opposite. Now, I know, this is wrong, but is that a problem of specifying cell zone conditions or boundary conditions? How can I deal with that?
