I sure don't get that out of the article:

“This new tactic uses a very short query, asking simply the name servers
for the ‘.' domain [a single dot],” he  wrote Monday in an analysis of

is large [or long]. A list of all the root domain name servers is sent
back in response."

That's exactly what we've been dealing with.
