Yes, the parking brake cannot affect the front brakes.

This is what I meant by you are correct. The parking brake has nothing to do with the hydraulic disc brake system. It uses a cable and a separate drum-shoe system that is built into the rear wheel(s). I am not even sure if is just a single wheel or not. In other words, it is a redundant system.
If you get on your brake pedal to stop the car and sit on the brakes after a session (say you decide to chat with someone on your way before parking and apply the brakes for a few minutes while doing so), then I guess you could warp the rotors since you might be affecting how the rotor cools and contracts. That is what I should have said earlier as opposed to referring to the parking brake. It's still not a good idea to engage your parking brake though.
