You are correct, this was a mistake on my part.  For what it's worth, I
just filed <https://bugs.torproject.org/31103> because of this.  Thanks
for bringing up this issue!

I agree, asking operators to choose their own OR and obfs4 port should
cause the least surprise.  It also serves as a reminder that both ports
need to be reachable for obfs4 to work.

I will update the obfs4 setup guide accordingly.

Cheers,
