Inheritance with Object.create() method in javascript [duplicate]

I was experimenting with Object.create() way of inheritance in Javascript.

While I clearly understand that this is how the inheritance is achieved using Object.create().

//Inheritance with Object.create()

function superClass(){
    this.name = "I'm a name in superclass";
  this.name2 = "Someone please pickup the phone.";
}

superClass.prototype.useMe = function(){
    this.name3 = "I'm name3";
  this.name4 = "I'm name4";
}

function subClass() {
    superClass.call(this);
}
subClass.prototype = Object.create(superClass.prototype);
subClass.prototype.constructor = subClass;
var obj = new subClass();

console.log(obj.constructor);

Output:
function subClass() {
    superClass.call(this);
}

The confusion arose when I moved the positioning of these two lines,

subClass.prototype = Object.create(superClass.prototype);
subClass.prototype.constructor = subClass;

See below,

//Inheritance with Object.create()

function superClass(){
    this.name = "I'm a name in superclass";
  this.name2 = "Someone please pickup the phone.";
}

superClass.prototype.useMe = function(){
    this.name3 = "I'm name3";
  this.name4 = "I'm name4";
}

function subClass() {
    superClass.call(this);
}

var obj = new subClass();
subClass.prototype = Object.create(superClass.prototype);
//I've commented the constructor assignment. 
//subClass.prototype.constructor = subClass;

console.log(obj.constructor);

Output:
function subClass() {
    superClass.call(this);
}

Isn't this suppose to return the constructor function as superClass as I commented the constructor assignment line.

Now, the question is; Is the positioning of subClass.prototype = Object.create(superClass.prototype); is really important?

Case 1: When I placed it above the object creation line, the assignment of new constructor function was required.

Case 2: When I placed it below the object creation line, I don't think we need the constructor assignment line, as it's clearly referencing the proper constructor function.

Thanks for the help.

Edit: I'm not mixing Object.create with constructor function. My only confusion was; when I placed the line subClass.prototype = Object.create(superClass); after the object creation, it should change the subClass.prototype.constructor to superClass's constructor. But it didn't it is taking the subClass's constructor. How? Or, am I missing something here.
