I'll take that one. Passenger obtained a cert to use on a specific itinerary. Passenger was involuntarily rerouted and hence unable to use that cert. Yes, passenger can reuse the cert on some other itinerary. But maybe passenger has no such travel planned, within the period of validity of the cert and compliant with the other restrictions of the cert (e.g. as to region, fare basis).
