Not at all clear - I can see why you are confused.

I don't think that the case described above is actually one of the
problem cases (there are others).  If by the 'downstream' connection,
they mean the proxy-origin connection, then it isn't a problem case.
If the origin server honored the Keep-Alive it would send a
Content-Length header in the response, and thus the end would not be
ambiguous.
