A license is a voluntary surrender of some rights by the author.

A license is not a contract between some third party,
such as CC or GNU, saying "by using this license,
you agree to NOT use any other license."
So I don't think ANY license is a "NoDual" license.

Alice owns her work as All Rights Reserved.
She decides to apply GNU-FDL to it.
She also decides to apply CC-SA to it.
She then also decides to license the same work
to MegaCorporation that doesn't have any copyleft
restrictions on it.

That she used GNU-FDL does not mean she can't use CC-SA.

And since she can put the work under two different
licenses, then Bob can come along and apply his
addition to both licensed versions.
