Can the Bases Be Cleared if They Are Not Full?

A basis clearing doubler triple, or even a basis clearing single, imagine something like that would be quite a time. You know, there is still a runner left on base, but all of the runners who were already on base at the start of that at bat are now back in the dugout. But so here's the thing, it cleared all the guys who were on base when when the hitter stepped into the batters box. So i think this one is ok.
