I see; the difference is SCOTUS vs. circuit court of appeals precedent. I was referring to the decision of May 9, 2014 that overrulled the Alsup court assertion that APIs are not subject to copyright. But that decision was not from SCOTUS but from the appeals court for the circuit.
Current status, if I understand correctly, is that SCOTUS has not weighed in on whether APIs may be subject to copyright, and precedent in (Edit: Ninth Circuit) should be that they are to be considered copyrightable (and, I suppose, "no precedent in this circuit or from the Supreme Court" in all other circuits).
