That figure is mostly the costs of running logistical chains in dangerous areas. It includes soldiers lost to attacks on convoys.
I doubt that less convoys will equal fewer attacks - it's just an accounting quirk that the casualties are apportioned to the fuel. The attacks might be less successful, as you won't be spreading the defence so thin, but you wouldn't get a linear reduction in costs.
