The red dragons that aid the gith are young adults at best. They gain combat experience and their fair share of wealth from aiding the gith, and the gith gain powerful (and very cool) mounts. Once they reach a certain age, they are free to retire and do red dragon things, while a new generation of young dragons replaces them - the one who's friends with Voss is an exception. If you view their relationship as transactional rather than rooted in obligation due to some ancient pact, it starts to make more sense.
