OPTIMIZATION : why LanguageManager.GetAllLanguages(false) is called even if it is not used?

      public Language WorkingLanguage
        {
            get
            {
                var customer = NopContext.Current.User;

                var publishedLanguages = LanguageManager.GetAllLanguages(false); // !!! Called here !!!

                if (customer != null)
                {
                    var customerLanguage = customer.Language;
                    if (customerLanguage != null && customerLanguage.Published)
                        return customerLanguage;
                }
                else if (CommonHelper.GetCookieInt("Nop.CustomerLanguage") > 0)
                {
                    var customerLanguage = LanguageManager.GetLanguageById(CommonHelper.GetCookieInt("Nop.CustomerLanguage"));
                    if (customerLanguage != null)
                        if (customerLanguage != null && customerLanguage.Published)
                            return customerLanguage;
                }

                // !!! Should be called here ? !!!

                foreach (var _language in publishedLanguages) // !!! Rarely used here !!!
                    return _language;

                throw new NopException("Languages could not be loaded");
            }
