Wow! Only those subject to the Pontiff can belong to this Church?

Sure, unless they have invincble mental impediments to joining.

I guess the RCC still teaches that Unum Sanctum is an infallible pronouncement.

Were you under some other impression?

Not really. I was just waiting for your very imaginative "Catholic Dictionary" explanation that Unum Sanctum doesn't mean what it says.
