I actually did this on purpose; I felt most people would never need more than one pool4 address, and those who did would pretty much never go for more than five or six. Bottlenecking a bunch of IPv6 clients behind very few IPv4 addresses is pretty much the whole reason why people would choose NAT64 over SIIT, I feel.

But this is counter-intuitive, lazy implementation and easy to fix.

Thanks to Edgar Rodríguez Bernal for reporting this.
