The lever is calibrated in the camera to move the aperture ring to the desired f/stop, at least for lenses from AIs onward where the aperture lever is also standardized. How would you know what f/stop you're using by moving the lever on the lens? It would be very imprecise. Yes it's a G lens. The AF-S designates what kind of focusing motor is in the lens. There are a few AF-S lenses with an aperture ring. That's not the case with mine, and I have a few.
Well you just estimate and then the camera meter would be pretty accurate otherwise do shoot, chimp and adjust. However, the level on old pre AI and AI lenses are not linear so it's hard to estimate. But from the AI-S onward the level is linear to the amount of movement so it's not too hard to estimate.
