If we apply the same logic as we did in that case, we can analyse the case where both Alice and Bob make an x measurement, and they both get the result `1`. Bob would then be able to apply observation 2 and infer that Alice would certainly have gotten a `0` if she had instead done a z measurement. Alice can do the same, inferring that Bob would have gotten a `1` if he'd have made a z measurement. So together they conclude that, if they had both made z measurements, they would both have gotten the output `0`.
