Does this mean traffic on the loopback interface will not traverse 
netfilter?

Yes this was already mentioned.

Only the SYN / SYNACK messages will

All data will bypass IP stack, qdisc (if any), loopback driver, and
netfilter.

These restrictions and any others should be documented in ip-sysctl.txt.

From Eric's earlier e-mail:

-> no iptables, 
   no qdisc (by default there is no qdisc on lo),
   no loopback stats (ifconfig lo).
   some SNMP stats missing as well (netstat -s)
