Catalog mode

[Inform-All]

I was wonder why according to Prestashop's core 'catalog_mode' is practically the same a 'show_prices'.
At the moment it has the same behaviour showPrices for a customer group means that customer group is in catalog mode.

    /**
     * @return bool
     */
    public static function isCatalogMode()
    {
        if (is_a(Context::getContext()->controller, 'FrontController')) {
            $isCatalogMode =
                Configuration::get('PS_CATALOG_MODE') ||
                !Configuration::showPrices() ||
                (Context::getContext()->controller->getRestrictedCountry() == Country::GEOLOC_CATALOG_MODE);
        } else {
            $isCatalogMode =
                Configuration::get('PS_CATALOG_MODE') ||
                !Configuration::showPrices();
        }

        return $isCatalogMode;
    }

Right now if you disable show prices (for any customer group) it has the same effect as catalog_mode for that customer group.
This makes no sense, if you wanna filter frontend.
