I believe this is incorrect.  I find no such restriction.  In addition,
in 14.7.3 - Explicit specialization [temp.expl.spec] we have:

   -17- A member or a member template may be nested within many enclosing
   class templates. If the declaration of an explicit specialization for
   such a member appears in namespace scope, the member declaration shall
   be preceded by a template<> for each enclosing class template that is
   explicitly specialized.

It would not be necessary to say "if" above if that were the only 
place it could appear.
