Oh dear. I see what has happened. Yes, that is a misleading paragraph in
the documentation, and I will do something about it. What it is
referring to is the case when an address gets aliased or expanded via a
.forward file. For example, an address could pass through an aliasfile
director, then a forwardfile director, and finally a localuser director.
This does not apply in the case of "unseen", which is really doing
something in parallel rather than serially. The word "unseen" is
appropriate - as far as subsequent directors go, that director in
invisible. An "unseen" director can be thought of as cloning the address
and handling one copy of it; the other copy carries on to subsequent
directors/routers.
