javascript module pattern returning return?

Question

Studying Module pattern in javascript and see below.. Question.. why do you need return inside of return? what purpose does that serve?

   var ex = function(){
        return {
            get: function(name){
                console.log("helloe " + name);
                return {
                    hostname: 'node1 '
                }
            }
        }
    }

Here you are returning an object literal.

var ex = function(){
    return {

Here you are declaring a function get inside that object literal.

get: function(name){

Here, you are returning an object literal each time the get function is called.

  return {
     hostname: 'node1 '
  }

understand this and appreciate it but I would love to see practical reason why this is call this way? I would think it's just simple to return {get: { hostname: 'node1'} } . what is the difference between that and return { get: function(name)}; return { hostname: 'node1'}} ??

Then I need to know what module system you are talking about, It does seam like an unnecessary complexity, do you have the links you are reading?
