I don't think there is any contradiction in wording. I think the source
of some of the confusion here is that Chris (and perhaps some others in
this discussion) seem to be giving "sublicense" a nonstandard
definition. If A, a copyright holder, conveys to B under the GPL +
additional permission, and B conveys to C without modification but
removes the additional permission (which, it may be noted, is authorized
by the terms of GPLv3), B is not "sublicensing" to C, because no rights
to the code are coming from B; they continue to pass directly from A.
"Sublicense" does not generally mean "cause your distributee to get a
proper subset of the permissions you got" (which I sense is the
definition Chris is assuming); rather, the sublicensor is engaged in a
distinct licensing relationship with the sublicensee in which a grant of
rights is made from the sublicensor to the sublicensee, possibly within
constraints defined in the original license. At any rate, this is the
notion of "sublicense" that is employed in the relevant clause of GPLv3.

Yes, that's precisely why that change was made.
