They are ultimately making a show to entertain the audience though. We only see sixty minutes of each day and that doesn’t begin to cover the constant individual interviews etc that are done each day.
A bit like Survivor, the editors will have the whole footage, boot order and winners all known to them before they even begin which will completely influence what we are and aren’t shown. In Survivor, the person leaving is often aware everyone is voting them and it’s a done deal but we are always shown two or three potentials backed with cuts of interview comments because otherwise it’s bloody boring for us to watch. So I’d imagine this is exactly the same?
