Unown G

[SuperWooper]

You have a Gardevoir Lv. X active, and a Pokemon benched with just 10 HP. If you were to use Bring Down, that Pokemon would be knocked out. If I attach Unown G to this heavily damaged Pokemon, am I correct in thinking that it would still be knocked out, in light of this recent ruling:

Q. Does Unown-G's "GUARD" Poke-POWER prevent effects from attacks that the
Unown-G is attached to?
A. No, the Poke-POWER only prevent effects from an opponent's attacks, not your
own (this will be addressed in future errata). (Feb 21, 2008 PUI Rules Team)

If it's your own Gardevoir attacking, correct.
