Your example is a router. As the page you quoted says "Envelope sender
addresses can be modified by Exim using two different facilities: the
errors_to option on a router (as shown in previous mailing list
examples), or the return_path option on a transport." If you want to
apply the modification on the router, you need "errors_to".
