ME HMVC + custom library + fetch_module() does not work right

I actually made the previous post more complicated than it needs to be to illustrate this bug. Here is an even simpler example:

class Test2 extends MX_Controller {

public function index() {
echo $this->router->fetch_module() . "<br />";
}
}

class Test1 extends MX_Controller {

public function index() {

$this->load->module('test2');
$this->test2->index();

echo $this->router->fetch_module() . "<br />";
}
}
