Ahhh.. but in an EMI filter, ground IS the RF ground.  I suspect that the
in/out difference is designed to allow the designer to make sure that the
noise stays on the inside of the box, and doesn't go through the wall of the
box via the ground wire.

In a TC app, it would make no difference, because there is no box
