Modules + Fascade + Mediator Combination in JavaScript

Question

I ended up reading an excellent article on http://addyosmani.com/largescalejavascript/

This article explains how to combine modules, facade, and pick together for a JavaScript application.

I can indicate what the article explains, but I don’t understand why I need to use the facade to access the intermediary.

I think that I can access the intermediary directly from my modules.

Please advise me ..

PS: Is that the right question?
