php + oop

Tenho os seguintes exemplos:

class a {

public $object_b;

public $value;

public function __construct() {

$this->object_b = new b(&$this);

$this->value = 1;



class b {

public $object_a;

public function __construct($a) {

$this->object_a = $a;

var_dump( $this->object_a );



$a = new a();

Ao fazer o var_dump, o value da classe a mantém-se a NULL, dado que à classe b lhe foi passado o endereço do objecto a, o value não devia estar a 1?
