  This gives us an apparent counterexample against the “long arm” functionalist theory. On Inverted Earth your experiences have the functional role that the functionalist theory says is necessary and sufficient for possessing \(Q_{R}\): they are “caused by red things in the right circumstances, and used in thought about red things and action with respect to red things rightly”. But on Inverted Earth your experiences with this functional role have \(Q_{G}\), not (or not always) \(Q_{R}\).
