I once repaired my Rolleigon 80mm and from what I remember, the shutter and aperture are mechanically free to move. They are directly controlled with a linear solenoid. Therefore, without any power, they can simply be moved. However, in order to do so, you need to open the back of the lens. I don't think that you can conclude anything about the condition of both body or lens from the position of the shutter. One only need to cut the current from then lens when the shutter is closed, for instance removing the battery when in mirror lockup.
