Why does CSRF cookie name = token name?

[eluser]arbme666[/eluser]
Ok I found this is Security.php in __construct()

Code:

// Append application specific cookie prefix to token name
$this->csrf_cookie_name = (config_item('cookie_prefix')) ? config_item('cookie_prefix').$this->csrf_token_name : $this->csrf_token_name;

Should it not be...

Code:

// Append application specific cookie prefix to token name
$this->csrf_token_name = (config_item('cookie_prefix')) ? config_item('cookie_prefix').$this->csrf_token_name : $this->csrf_token_name;

Thanks
