Not sure which entity you are refering too... 'as-override' (applied
on AS3) replaces the customer as w/ the provider as. As such it does
not change in any way the loop detection mechanism in the provider
network and it avoids having to have the customer network (AS2 in this
case) set 'loops' to 2.

The issues that you are raising would show up by configuring 'loops 2'
on AS2... not by doing as-override, afaik.
