In history constraint validation $account object is modified

In function password_policy_constraint_history_validate($password, $constraint, $account) the $account object is modified which causes some problem when we use the password_policy_validate to custom forms. In my case I am using the Password Reset Landing Page (PRLP) module and I am adding password_policy_password_validate() to user_reset_form and since the password_policy_constraint_history_validate alters the $account object, it causes the PRLP module to fail. So I patched the code as follow to restore the original password.

function password_policy_constraint_history_validate($password, $constraint, $account) {
      require_once DRUPAL_ROOT . '/' . variable_get('password_inc', 'includes/password.inc');
     $old_passwords = _password_policy_constraint_history_old_passwords($constraint, $account->uid);


// Storing org pass
     $org_pass = $account->pass;</strong>

     foreach ($old_passwords as $pw) {
       $account->pass = $pw;
       if (user_check_password($password, $account)) {

//Restoring org pass
	account->pass = $org_pass;

      return FALSE;
    }
  }

//Restoring org pass
   $account->pass = $org_pass;

  return TRUE;
}
