Here's the bit I'm querying:

"If your product incorporates any code licensed under GPL v3 your product has to be licensed under [GPL] v3"

Now, if your product is "SuSE Linux 10.0" or whatever, that statement is clearly not true, as the product in question is comprised of a number of components which have various licences, including GPL v2, GPL v3, X11, Artistic, MPL, SPL, Apache and BSD licences - and probably more.

Just because GNU textutils or whatever has been relicenced under GPL v3 has no bearing whatsoever on the licencing of, say, X11.
