Any reason for using collection to retrieve single address instead of using load method of model?

OrderController.php

// From app/code/core/Mage/Adminhtml/controllers/Sales/OrderController.php
    /**
     * Edit order address form
     */
    public function addressAction()
    {
        $addressId = $this->getRequest()->getParam('address_id');
        $address = Mage::getModel('sales/order_address')
            ->getCollection()
            ->addFilter('entity_id', $addressId)
            ->getItemById($addressId);
        if ($address) {
            Mage::register('order_address', $address);
            $this->loadLayout();
            // Do not display VAT validation button on edit order address form
            $addressFormContainer = $this->getLayout()->getBlock('sales_order_address.form.container');
            if ($addressFormContainer) {
                $addressFormContainer->getChild('form')->setDisplayVatValidationButton(false);
            }

            $this->renderLayout();
        } else {
            $this->_redirect('*/*/');
        }
    }

Has been fixed in Mage+ apparently mageplus/mageplus@b4332cd
