CodeIgniter/DataMapper: reuse object

Question

I use this to count all active users in a database, works like it should:

$ouser = new User;
$data['users_active'] = $ouser->where(array('active'=>1))->count();

Now I also want to use the (same) object to count all inactive users, therefore I want to use this:

$ouser = new User;
$data['users_active'] = $ouser->where(array('active'=>1))->count();
$data['users_inactive'] = $ouser->where(array('active'=>0))->count();

But this doesn't seem to work. Clearing the object first doesn't work either:

$ouser = new User;
$data['users_active'] = $ouser->where(array('active'=>1))->count();
$ouser->clear();
$data['users_inactive'] = $ouser->where(array('active'=>0))->count();

How can I resuse the same object, in this case for counting?
