Yeah, sorry I think we're going over old ground here and I've confused you againThere's a physical linkage on the OM1 that pushes the stop down lever in the lens. That linkage is connected to the mirror/shutter in the camera body so the lens stays wide open until you take the shot. On a digital body, the adaptor has a small bar built in that permanently presses the stop down lever in the lens. As a result, as soon as you turn the aperture dial on the lens, the blades stop down.
