Magento's $_weeeHelper-typeOfDisplay() Method

Question

I'm investigating Magento's infamous price block/`price.phtml` file, and I've run into something that looks like a bug and/or abandoned code path, but I'd like to run it by the community first to make sure I understand what's happening. Throughout this file, Magento will use the following method in conditional calls ``` $_weeeHelper->typeOfDisplay($_product, 0) $_weeeHelper->typeOfDisplay($_product, 1) $_weeeHelper->typeOfDisplay($_product, 4) $_weeeHelper->typeOfDisplay($_product, 2) ``` From what my code tracing has gathered, this method (as called) ultimately compares the second paramater with one of two configuration values.

    {
        return array(
            array('value'=>0, 'label'=>Mage::helper('weee')->__('Including FPT only')),
            array('value'=>1, 'label'=>Mage::helper('weee')->__('Including FPT and FPT description [excl. FPT VAT]')),
            array('value'=>4, 'label'=>Mage::helper('weee')->__('Including FPT and FPT description [incl. FPT VAT]')),
            array('value'=>2, 'label'=>Mage::helper('weee')->__('Excluding FPT, FPT description, final price')),
            array('value'=>3, 'label'=>Mage::helper('weee')->__('Excluding FPT')),
        );
    }

}
