This. This is the way things should be. For some reason, the West decided the opposite and Saga's were considering small chunks of a larger story when it comes to Dragon Ball. You can just look at it's wiki for proof, it always confused me (I think they actually marketed like that which is why but I don't know).I always looked at it as the "Saga" being the whole that is divided into arcs.
So the Android Saga is made up of two arcs, the Android Arc and the Cell Arc.
