Essentially, all this means is that you can do what you like with the
code, except claim another Copyright for it, or claim that it is issued
under a different license.

Is this an issue? In what way are we *not* claiming it is issued under
a different license?
It is my understanding that we can ship code with a BSD license, as long
as we explicitly document it. That is, we need to document it in the
notices file etc. This is not to say that we necessarily want to ship
the snowball stemmers with the core release right now, but I think in
principle there is no problem with the BSD license. For example, check
the recent Felix release, they ship code under a variety of licenses.
