I don't know whether the piston re centers itself once equal pressure is established in both circuits. I have never had to manually push the piston back in place; but, I have always flushed / bled the system using a pressure bleeder.
If the end of the plastic pin does not look mangled and the brake system warning light is not staying on after you release the parking brake, then you are probably good to go. If the warning light is staying on, then you know where to look first.
