As I read it, it says that you cannot use any of the given repeat devices if the pedallings are different in the repeat than in the original. I would extend that to mean that you may use the device if there is no new pedalling indication. I think 20.11 is meant to differentiate these devices from the full and part measure repeats, so I think you would not restate a pedal marking before the number sign or after the number.
