[Mediawiki-i18n] Why why /** Message documentation (Message documentation)?

[S Page]

Almost every extension's i18n.php file has

/** Message documentation (Message documentation)
 * @author Some Person
 */
$messages['qqq'] = array(
    ...

Why repeat it?

Is it because the header for each language section is "/** French
(français)" , so Qqq is being consistent? But the English header is just
/** English.

Does some undocumented tool in maintenance/language rely on the format of
these headings?

Thanks for any insight.
