Actually, assuming the browsers involved discard unknown declarations 
like they're supposed to, this would work (in either order, even):

   -w3c-background-origin: border-box;
   -w3c-background-origin: border;

But in a situation in which the meaning of the syntax changed without 
changing the allowed value set you would be absolutely correct.
