Ok I have to say I understand what you saying now. I assume you mean the blue belt in the diagram. This is not an accurate routing in this picture, I should have probably mentioned that the mock up picture was not anatomically correct.

Yes, the auxiliary drive belt is routed in a way that the idler pulley, containing the water pump, is rotated in turn with the alternator and power steering pump. Power steering pump is missing from the engine in the picture. I reckon a good tuner, loads round here, could knock up a custom map.
