constraints together and animation

[Antodima77]

Good morning to all I wanted to ask if someone knew how to do this:
I would like to, having two parallelepipeds coincident on the same face that in the moment of animation it did not move only one face respect the other fixed, but that both faces died of the same amount respect the plan of support.
You can do it.
thanks in advance

If I understand correctly, you can simply use symetry constrain:
