You're confusing the permissions notice, which allows a disjunction of
template licenses, with the template licenses themselves, each of
which individually must remain unchanged.  The "or later" phrasing is
simply a compact way to express what legally is a multiple license,
akin to the GPL+FDL licensing recommended by the FSF for code examples
in documentation.
