Difference between facade and module pattern

I was going through this article and i am confused on the diff between facade and module pattern.

var MyModule = ( function( window, undefined ) {

  // revealing module pattern ftw
  function MyModule() {

    function someMethod() {
      alert( 'some method' );
    }

    function someOtherMethod() {
      alert( 'some other method' );
    }

    // expose publicly available methods
    return {

      // in our normal revealing module pattern, we'd do the following:
      someMethod : someMethod,

      // in the facade pattern, we mask the internals so no one has direct access by doing this:
      someMethod : function() {
        someMethod();
      }

    };

  }

} )( window );

In both the ways we are actually calling the same function which is private. What big deal does facade provides?.
