Yes it would defeat it. The only reason I can think of to require hair
pinning of traffic between downstream on-link peer CPE is if your
default router is your traffic billing point, and you want to bill
(count) the traffic between those CPE. Otherwise you're
probably unnecessarily forcing a P2P model connectivity model (i.e.
an ATM ADSL backhaul model) onto a multi-access technology (an
Ethernet/ADSL backhaul model).
