Zend Framework Validator Chain messages - validation

Question

Struggling to understand why my validator chain is showing the incorrect message for the value I type in.
Currently my model's code is making the incorrect message appear when I type in non-identical passwords instead of just the expected 3rd message ('Please retype password between 8-25 alphanumeric characters and matching the first password' when expecting 'Retyped password must match first.') when i type in mismatched passwords of 8 -25 characters long.
$password2 is the one giving issues
Also unsure if the indentical validator is working due to this problem.
Zend Framework version 1.11
Specific code chunk related to above
$password2 = new Zend_Form_Element_Password('password2');
$password2->setAttrib('size', 25);
$password2->setRequired(true);
$validatorChain2 = new Zend_Validate();
$validatorChain2->addValidator(new Zend_Validate_StringLength(array('min' => 8,'max' => 25)), true);
$validatorChain2->addValidator(new Zend_Validate_Alnum(false), true);
$validatorChain2->addValidator(new Zend_Validate_Identical('password1'), true);
$password2->addValidator($validatorChain2);
$password2->addErrorMessage('Please retype password between 8-25 alphanumeric characters and matching the first password');
$password2->addErrorMessage('Passwords can only be alphanumeric characters.');
$password2->addErrorMessage('Retyped password must match first.');

$submit = new Zend_Form_Element_Submit('submit'); // Added submit button

$submit->removeDecorator('DtDdWrapper'); // Remove the default DD div wrapper
$this->setDecorators( array( array('ViewScript',
array('viewScript' => '_register.phtml')))); // The form html page
$this->addElements(array($email, $firstname, $surname, $password1, $password2, $submit)); // Add all the form elements
}
}

You should instantiate it like this...
$validatorChain2->addValidator(new Zend_Validate_Identical(array('token' => 'password1', 'messages' => ....)), true);
