Yes but the confusing thing is that the battery will have to be recharged at some point... presumably on the next start. So the thought would be that the system would have to run extra to recharge the battery and you'd lose the advantage.

However.... the engine will have to run for at least 30 sec on the next restart, and probably longer to heat up the water temperature.... during that time the engine is running anyway and can recharge the battery. So in the end the engine doesn't have to run an extra amount of time to get back to a charge.
