Yes. Court cases only apply within their jurisdictions - not beyond.
That the two cases result in different RKBA results from the rest of the country creates an "equal protection" problem which only SCOTUS can resolve (and will likely find the narrowest possible, and thus very unpalatable, solution to).
IANAL, but I belive that this decision (once it's fully adjudicated), can be introduced in litigation in other venues. I don't think it would carry the same weight as case law from their own jurisdiction, or, from the SCOTUS, but I believe that such things are regularly included in the arguments (i.e., thus and such a court in thus and such a jurisdiction said thus and such on a matter related to the one before this court).
