Comment (by kaie):
The information below was the source of my confusion.

'The "ExtORPort auto" above is fine -- the extended ORPort is for local
connections, and you don't need to open anything in your external
firewall.'
It seems that statement isn't right. It seems the extended ORPort isn't
restricted to local (localhost-only) connections, but rather it's used to
listen for incoming connections from other computers, that want to use
this server as a bridge.
The ports that "ExtORPort auto" allocates will listen on all network
interfaces, not just localhost.
In my understanding, the automatically assigned ExtORPort must be
accessible from the outside (and if a firewall is used, the firewall must
allow incoming connections on that port(s)).
