This binding in node.js

I am puzzled by some node.js behaviour, which is different fron Google Console.

Here is a simple code

var t = "GLOBAL";
var objet = {
  t : "LOCAL1",
  test : function() {
    console.log(this.t,t);
  }
};
var objet2 = {
  t : "LOCAL2",
  test : objet.test
};
var test = objet.test;
objet.test();
objet2.test();
test();

This code yiels different result.

In node.js, i have these results :

LOCAL1 GLOBAL
LOCAL2 GLOBAL
undefined 'GLOBAL'

In chrome console :

LOCAL1 GLOBAL 
LOCAL2 GLOBAL 
GLOBAL GLOBAL 

I thought that calling directly the function binded to test.t, this would be binded to the global scope, it is the case in chrome, but node in node.js.

Note that if i remove the varin the first line, the node.js version give the same result.

So what is going one ? It seems that there is a scope in node.js that i am missing ? Does somebody have a clue ?
