another head scratcher

I was listening to a hypnosis CD and the author has a very simple name, like Joe T. Smith.

But every time he says his name at the beginning of his CDs, he emphasizes the "T", as if he's afraid we're going to confuse him with Joe P. Smith, the hypnotist or Joe G. Smith, the hypnotist.

Why do we even need to know his middle initial?

Weird stuff like that has a tendency to distract me. As does shiny objects....
