Correct, any reroute must be legal without an extension at the time it is assigned. After that all the normal FDP limits and extensions apply.
Many times this is why you cannot be put back on your original delayed flight that you were rerouted out of. Once you have your reroute schedule any further change must be legal without the extension, even if it was on your schedule earlier in the day.
