Traffic Assymetry of traffic which requires (for lack of better term)
"transport" to the destination.  In the case of longest-exit routing,
the traffic received doesn't require much transit, nor in the case of
distributed content.

Presuming shortest-exit, correct.

It's difficult to "know" whether the distribution is actually
working and resulting in interconnecti traffic which is local,
but otherwise, yes.
