Ah! I see now. Thank you very much for taking the time to reply.
Well, you're right that the update should still not show up, based on the KB. So I would bring that to Microsoft's attention, if I were you.
As for your setup, well, it's not how I would do it. And it's probably not keeping with best practices. But I assume you have a good reason for doing it that way. After all, people don't deploy configurations that result in more work without a damned good reason!
What I would suggest is maybe a GPO to apply the required registry values to those machines you want to block GWX on. Seems simplest, and should work.
