No, it doesn’t. Because the Court expressly declined to examine the question, the CAFC decision is binding only where it would have been without the Supreme Court decision, i.e., those courts bound by the CAFC’s interpration of how Ninth Circuit law applies. As it turns out, that is exactly zero courts.
The reason the Supreme Court often likes to find the narrowest grounds possible for a decision is to avoid making more binding case law than is called for; giving the lower court rulings on all questions not addressed (including those the Supreme Court explicitly avoids) the same binding effect as the actual Supreme Court holding would defeat the purpose, and it is very much not how things work.
