With most cars having an on board computer these days, if the battery is disconnected and replaced without using a backup battery all custom settings made by the customer will be lost, that's what happens with my Mercedes anyway.
So leaving the car running would achieve this result of backing up the battery voltage whilst it is being changed.
May be this is why they left the car running but it sounds a bit risky to me what with all the transients at the time of switch over.

It's not the least charm of a theory that it is refutable. The hundred-times-refuted theory of "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it - Friedrich Nietzsche
