Yes, that's why it is not binding elsewhere, which doesn't mean it has no effect. Particularly, if another Circuit has not issued a conflicting ruling, the Ninth Circuit ruling can be cited in and relied on by trial courts in that circuit as persuasive, rather than binding, precedent, so it can have an impact from the very earliest stages of the process.

A circuit split is also a reason for the Supreme Court to take a case, so the Ninth Circuit decision, without being binding, makes it less likely that any conflicting decision by another circuit will be the final resolution of the case in which that conflicting decision is issued, which is an important effect at the other end of the process.
