What would be the purpose of yielding control from the thread and tell it to wait, rather than just let it run to completion?

Maybe I misunderstand you, but telling the thread to halt is surely a waste of those resources?

Because sometimes you need to sync the entire program state, or some subset of the state, to make measurements or to let disparate parts of the system interact
