The tutorial says: 

"All messages are logged through the kernel facility. In other words, setting kern.=info /var/log/iptables in your syslog.conf file and then letting all your LOG messages in iptables use log level info, would make all messages appear in the /var/log/iptables file. Note that there may be other messages here as well from other parts of the kernel that uses the info priority. "

AFIAK iptables uses the kernel logger (with printk) and doesn't support syslog directly, that's why the facility can't be specified.

An alternative solution would be to use syslog-ng.
