I believe we've seen bogus low AS number announcements a few times
before, and they've usually been caused by attemts to configure
AS path prepending without understanding and/or reading the docs.
Someone might have wrongly assumed that

could be written shorter like
set as-path prepend 133711 2
and there you go...
