I don't believe that it's data dependent. Rather in your example the 
same memory-space is used for those two objects because they don't exist 
in parallel. The first is cleared before the second is instantiated.

<?
    $x = new stdClass();
    $y = new stdClass();

    var_dump(spl_object_hash($x), spl_object_hash($y));
?>

This yields a difference.
