It's mostly to allow the reverse proxy on localhost to connect to the container/service, while blocking all other hosts/IPs.
This is especially important when using docker as it messes with iptables and can circumvent firewall like e.g. ufw.
You're right that it doesn't increase security on case of a compromised container. It's just about outside connections.
OK, yah, that's what I was getting at.
