Zend_Auth persisiting auth data. buggy? documentation wrong example?

[Julian Davchev]

Hi,
Is it just me or this example is wrong    and      stuff is stored right
after   $this->_auth->authenticate($adapter);

http://framework.zend.com/manual/en/zend.auth.adapter.dbtable.html#zend.auth.adapter.dbtable.advanced.storing_result_row

I am using this case......and I got stuff persisted way before...
this->_auth->getStorage()->write(...........)
