Except it doesn't. Because no-one on that thread made the claim that it
is. There's absolutely nothing in the thread (except maybe earlier
instances of him and you misrepresenting others' claims) about 'y' being
a name reference to 'x', so there's nothing in that thread for it to
reasonably refer to.
