A very nicely told story, and very puzzling.  Both the starter and 
the generator, running as a motor, would tend to turn the engine CW 
(as viewed from the rear.)  The generator doesn't have enough torque 
to do this, however; you can stop it with your hand.

I have seen starters get stuck, either due to a fault in the starter, 
or a fault in the ignition switch, but of course this always results 
in a CW rotation.

One of my favorite stories was about a friend who's ignition switch 
return spring was shot.  He had gotten used to returning the key from 
the START position to the RUN position by hand once the engine 
started.  He forgot to mention this to a woman friend that he loaned 
the car to, however.  She started the car and proceeded to drive 
about 10 miles at 60 mph when her drive was suddenly interrupted by a 
loud BANG.  The starter armature had finally exploded from being 
continually over-revved.  When she tried to restart the engine there 
was no response at all (surprise, surprise.)

Thinking that I might find enough to be salvagable, I offered to try 
to rebuild the starter.  When I opened it up the hollow shell of the 
starter was filled with what appeared to be copper colored sand, and 
nothing else.  I sent it back to Bosch as a core.  I don't think they 
made much on that rebuild.
