PS-3 doesn't care about polarity, but if the wires are reversed after the TIU, the DCS signal would be on the outside rails which are not always connected depending how the blocks are set up, especially for non-derailing switch operation, no?

Well a minor issue is you said earlier DCS was only on the center rail and IMO that is wrong.

DCS is a signal embedded in the power on the rails. So no, it's on BOTH rails middle and outside.

TMCC is a radio signal. A lower frequency one, but a Radio signal. That radio signal, the outside rails form one half, the house wiring is the other half.

DCS is an in-band signal and again, is the difference between the 2 rails electrically.
