Misleading error messages about bind_ipv4_only and bind_ipv6_only?

      if (bind_ipv4_only && tor_addr_family(&addr) == AF_INET6) {
        log_warn(LD_CONFIG, "Could not interpret %sPort address as IPv6",
                 portname);
        goto err;
      }

Is this warn mixed up? Same with the one below it.
