now that is certainly strange. I have never seen this before.

the most complete reference:
1) the bgpd.conf(5) manpage
2) the /etc/bgpd.conf sample config
3) /usr/src/usr.sbin/bgpd/parse.y ;)

not at all, it looks perfectly fine.

this... well, this does not make too much sense. bgpd relies on
established tcp sessions, this is not going to fly.
The Way To Go (tm) is a second machine running bgpd with a second pair
of sessions. It would be neat to couple advertising the network(s) in
