It’s obvious to me, very obvious in fact, that the entry is signed by a guy named Roy. Someone then added “Moore, DA and the rest. The number 7s are different than the ones above.
It would be easy to just check the yearbook for another guy named Ray.
Who knows what reality is here, but if I were on a jury evaluating this piece of evidence, I would have to say that the yearbook signature is nowhere near conclusive to prove anything about Judge Moore.
