Bingo! That is your answer. It is a mechanical thing and that is way D mount lenses are. It doesn’t make any sense, common or otherwise, but as they say, “It is what it is.”
It seems like some have attacked my answer. I thought it was possible I was mistaken so I checked and I was wrong when I thought I was wrong. So here is why I gave that advice. In late 1993 I purchased a N-90 which was kitted with the 50mm f/1.8 D. I purchased this camera to replace a Honeywell, rebranded Pentax in US, with a screw mount. I also bought the f/2.8 Trinity in D mount.
My current camera is a D-7100 that retained the screw focus drive. I went to my grab and go bag which has a 18-200 zoom mounted on the camera and the 50 mm f/1.8 D and 35mm f/1.8 which fit nicely in cargo pockets. Oh, and a nearly discharged battery which is now on charge.
I put the 50mm, pictured below, on the camera. This is the one we are talking about? If it is set as shown it works just fine. If you unlock the aperture but leave the setting on f/22 it works. If you change the aperture if will flash fEE. QED! BTW You cannot close the lock button unless the aperture is set to f/22. I might add that villains occasionally change that aperture so I see fEE.
I did not mess with menus because cameras didn’t have menus when those lenses were released.

I am one who doesn't have common sense but it does make a lot of sense that you have to set the aperture ring to the minimum aperture if you want to control the aperture via the sub command dial.
I prefer using the sub command dial as I can see the changes in the viewfinder...I don't have to take my eye away from the viewfinder to check the top LCD or look at the lens to see what I have chosen.
Works the best for me.

On the D800 if the op chooses to set the aperture via the aperture ring the aperture is still visible in the viewfinder except that it only in full stop increments and not 1/3 stop increments.
