The behaviour when a falsy value is passed as the $locale is undocumented, but it appears that it returns the primary language of the default system language. In my case:
Locale::getPrimaryLanguage(null);
Returns 'en'. So make sure to test $locale before passing it to the method.
Locale::getPrimaryLanguage
locale_get_primary_language
(PHP 5 >= 5.3.0, PHP 7, PECL intl >= 1.0.0)
Locale::getPrimaryLanguage -- locale_get_primary_language — Gets the primary language for the input locale
