Hmmm. I see what you mean. And given Mia's comment on the intent of the 
CC licenses, this may be the case for the CC licenses as well.

So do we really need a dual distribution clause anyway? Is it in fact 
the requirement to provide an unencumbered copy that is not currently 
present in the license and would require a dual distibution clause to 

Oh, the irony if that is the case. :-)

But then we get on to who can legally add DRM to a work.

But if everyone is allowed to apply DRM to modified versions of the work 
they do not need to receive DRM versions of the work as they can apply 
the DRM to the original version themselves.
