Advertising your own prefixes is actually matched by filtering on the
path ^$ in Cisco regex speak - read: "the empty path".
So, it is a slightly complicated way to formulate the thing, but it is
correct - a nonempty path means "transit for other ASes", and the empty
path is "yourself". On outbound.
Your peer, on inbound, won't see an empty path of course.
