Can't join the same table twice..

Hello.

How is it that, when i try to join a table twice, it only joins the second table, and ignores the first one?

This is my code:

$user = self::query()
        ->columns(array('COUNT(today.day) as day', 'COUNT(month.month) as month', 'Users.id'))
        ->join('Blogs', 'Users.id = Blogs.userid')

        ->join('Statistics', 'Blogs.id = today.blogid AND today.day = 22', 'today') // THIS get's replaced...
        ->join('Statistics', 'Blogs.id = month.blogid AND month.month = 1', 'month') // THIS works

        ->where('Users.id = :userid:', array('userid' => $id))
        ->orderBy('Users.id DESC')
        ->limit('1')
        ->execute();

    return $user;
