I have seen that airlines do not follow this rule for award tickets (many give 12 months from the issue date only) but I guess this has to do with the nature such tickets.
I've definitely had AA hold me to 12 months from date of issue before, and that was for international, but was not a DONEx ticket. I don't know if that's different or not, but if it were 1 year from date of first flight I'd have had another 3 or 4 months on it.
