Finwitch:

I think they ARE one and same, and only perspective changes. They 
seem to be different when Hermione says things like you can't 
apparate or disapparate in Hogwarts... meaning that both directions  
are prevented.

There could be shields that permit apparating a place, but not 
disapparating (like a fish-trap), possibly even some that prevent 
apparating but not disapparating. (useful if you need a place where 
none can suddenly enter, but you can LEAVE quickly - if you have need 
to see who's coming but don't care who's leaving...). Of course, most 
places have neither.
