If I unload 200 bu wagon load of grain into a 1000 bu bin which had been empty I have completely unloaded that wagon. It wasn't the wagon that unloaded itself but it was I who did it. When I completed unloading that wagon it was complete and wouldn't need to be done again. That did NOT fill that 1000bu bin.
Respectfully, I don’t understand your example and its connection to the thread.
