Sounds completely bogus to me.

The cookie is typically generated by the server, as a response to an 
authentication event (single or multi-factor). The cookie is then used 
to maintain that authentication from request to request.

There is NO authentication component in such a cookie. It is created by 
the SERVER, and as such CANNOT qualify as an authentication factor at all.
