Well, that's easy enough to deal with. Just say that you can carry extra fuel without any tankage (since antimatter is only around 1 part per million of AM-boosted fuel), but such fuel only can be used in air-ram mode (and that fuel is mandatory for antimatter air rams).

For the antimatter thermal and plasma engines, the M/AM reaction is just used to heat hydrogen or water reaction mass. AM pion is the only engine that uses matter/antimatter directly for propulsion.
