The term "recognize" in this context likely means to "acknowledge the existence, legality, or acceptance" of a thing. This isn't legal, but I could acknowledge the existence of some NC claim obviously without accepting it. My personal acceptance of some Auburn claim to an NC is pretty irrelevant, so I don't give it any/much thought (unless someone points to some specific with data). The claim exists, so I acknowledge that far.
Do I accept it? No, I don't, aside from someone pointing out some claim they previously had not made and now make with the history behind it. But, my "analysis" is obviously moot. They can claim whatever they want, and my life goes on undeterred. It can make for some discussion for those interested in such things. I'm not.
