Method overriding and Inheritance in java

Consider the following code segment:

class A{ /* assume static and non static block are here */ }
class B extends A{ /* assume static and non static block are here */ }

In main method,

 new B();

So the order of the initialization would be :

1. static members initialization for class A
2. static members initialization for class B
3. non static members initialization for class A
4. then execute the code inside constructor A
5. non static members initialization for class B
6. then execute the code inside constructor B

Now take a look at this code segment,

class A{
    A(){
        this.m(); //line 1
    }

    void m(){
        System.out.println("A.m()");
    }
  }

  class B extends A{
     void m(){
        System.out.println("B.m()");
    }
  }

In main method,

 new B();

When the code of constructor A is being executed, it can only see the method m in class A since non static members hasn't been initialized yet for class B (according to the order I mentioned). However the result is "B.m()". (method of sub class has been executed) Can someone explain what is happening here(method overridng) considering the order that I have mentioned ?
