Redux Auth - is it dead?

[eluser]klompie[/eluser]
i downloaded the most recent version from http://github.com/benedmunds/CodeIgniter-Ion-Auth

return (bool) $user_group == $admin_group;

isn't this casting the $user_group as bool? and not the complete $user_group == $admin_group?

When using:
return (bool)($user_group == $admin_group);
or
return (bool) $user_group == $admin_group;
it works like it should do.

But when using:
return (bool) $user_group == $admin_group;
every group is returning true
