It is, and you are right. But that is not the goal. He wants to spin them down and then *keep them spun down.* Thus, an hour a day of driving is better than driving all day or start/drive/stop all day.
This was his original problem, sync was causing his drives to spin back up, when he wanted them to stay down.
