That is a long-standing puzzle.  Since they don't follow our halachot, why
do we assume that cooking wine -- even boiling the life out of it -- would
prevent them from using it for nisuch.  And yet that is exactly what we do
assume.  I can only conclude that if it's pasul for our nisuch, then
whatever they do with it doesn't count halachically as nisuch laA"Z, so
we don't care. They can call whatever they do whatever they like, but we
don't call it nisuch, so the wine remains permitted.
