Because neither DIRF nor Tech1 meets the requirements of AOW by any agency I'm aware of. AOW typically includes deep, night, navigation and something else like equipment or nitrox.
Just do a 2 weekend AOW and be done with it. If you want to take GUE classes take them - they aren't about the cards which may or may not be accepted by an operator anyway.
