Ah! Thank you very much! This statement cleared up my confusion. I
didn't see this statement in any documentation, but I could have missed it.

Nice to know that, as I do use FreeBSD. I'm still a bit curious; why
would I want two separate sockets when I am already listening on 0.0.0.0?

At first glance, I'd think the emulation suits my needs more; no sense
in taking up memory for an extra socket right?
