"Crazy" is probably the wrong word for me to use (I have been known for my hyperbole in speech). What I meant was that, from my point of view, having multiple depots is almost the same as having multiple directories at the root of a single depot. The Perforce Support article you linked to says the same thing.

Hence, I feel that having multiple depots on one Perforce server simply eats up client names and causes confusion among those who haven't learned the distinction between "depot" and "server".
