shared topology does give shared cells on the interface but interfaces are respected!

  Hi
  I am meshing three bodies for multiple reference frame method, two (rotary, for two rotors) being encompassed in the other one (stationary). Thus, I have two interfaces. Like this:

  Answering my own question:
  Those so-called "bad" cells are there because you have chosen the"hex core" option in the "method" windows. Changing "hex core"to "hex dominant" fixes your problem. I guess the terms speak for the difference between them.

  Hex Dominant meshing is appropriate for Structural models because we care about the mesh quality on the surface of the part, and can tolerate poor element shapes on the interior.
  Hex Dominant meshing should never be used for CFD meshing because you can't tolerate poor element shapes on the interior.
