It doesn't though, I just didn't explain how that role works. Consider the "leader" as the lead coordinator rather than someone barking orders.
Once all of the debate is over, a decision needs to be made and followed through with, with the understanding that new information will require tweaks or wholesale re-evaluation of the plan until completion.
So in that sense, the leader ensures that everyone is executing their role well, and that everyone is aware of any deviations to it - while also delegating authority or decision making as needed as the task unfolds.
It's way more nuanced and delicate than it would seem from the outside.
