Thinking about this longer: it probably isn't.  Suppose we have a path:
source, intermediate devices, destination.  The source sends one packet,
an intermediate device duplicates it, destination gets two copies.  This
is duplication, but it fails the definition above.   So, I'd rephrase
it into:

   + both appear to have been sent by one and the same host, to one
     and the same destination

This covers the case above.  (Funny that definining something obvious
is so complicated).
