1. Why?
2. Was the purge run? I fear not:

Article.php uses

$request = $this->getContext()->getRequest();
$purge = $request->getVal( 'action' ) == 'purge';

Test yourself: Add this console.log to it and run action=purge

echo "<script>console.log('action: ". $request->getVal( 'action' ) ."');</script>";

Confirmed on 1.22.12 and latest on mediawiki.org

Sorry if this is false alarm but nobody was able to answer me this and need to to check action=purge for flushing memcache.
