It is not really the middle of nowhere. It is at the edge of the 
Potsdam city quarter Am Stern. Anyway, I think that the main purpose 
of letting a bus service end here was to give good connections to the 
GDR public transport buses. The street that crosses the motorway at 
junction Potsdam-Babelsberg (for this is the one we're talking about) 
is an important one with buses going into Potsdam, and towards 
Stahnsdorf.
Why the service was more frequent at weekends? Maybe because of West 
Berlin daytrippers, but possibly also to give them the opportunity of 
visiting the large cemeteries. This was always a problem in Cold War 
Berlin: many people had relatives that were buried on cemeteries 
outside of West Berlin. A big one is the Wilmersdorf Waldfriedhof, 
combined with the Suedwestkirchhof der Berliner Synode, very near the 
motorway exit (in fact, only the Wueste Mark lies in between). If you 
look at the site I mailed earlier on, there was even a special 
railway built to this cemetery, running from West Berlin (which was 
subsequently put out of business by the East Germans, of course). I 
wouldn't be surprised if line E was allowed only that much inside the 
GDR to give connection to another (GDR) bus service, so that the 
travelers would have to pay once more for a bus, but now to the East 
Germans...
