Quite.  It's a convention.  As the distributor will only fully engage with 
the drive gear in one position it is only of use when changing caps ... or 
removing plug leads from cap and/or plugs ... or installing a different 
distributor ... Come to think of it that's quite a few 'only's, and a bit 
like 'What did the Romans do for us?'.

However with the distributor inserted and the drive dog engaged with the 
gear you can turn the body all you like but the rotor won't move.  That's 
why you have to move the leads round the cap if the distributor assembly or 
drive gear orientation aren't as they were when the engine last ran.
