Declaring this by fiat to be so doesn't make it so. If in some community of users a typeform distinction for @ is introduced with different forms for lowercase and uppercase contexts, then it is entirely possible that what you deem to be a caseless symbol may become for that community a bicameral character pair. So, to say that John is comparing apples and oranges is certainly begging the question.
In fact, I can point you to instances in which @ has been used as a lowercase word-forming letter with an uppercase pair. (Of course, this is among the worst orthographic innovations imaginable.)
