Ion Auth - Lightweight Auth System based on Redux Auth 2

[eluser]ladooboy[/eluser]

Code:

if (!$this->logged_in() && get_cookie('identity') && get_cookie('remember_code'))
        {
            
            $this->ci->ion_auth_model->login_remembered_user();
        }

Found out that the $this->logged_in() function always returns TRUE when you're logged in(obviously). May I ask what the reason is here for checking if it's FALSE ?
