Spencer's confusion is with the word "endpoints" in the second quote,
and I don't think this change fixes that, as "client and server" can
also be misconstrued (and even with the "of a single connection"
there, they might be).

Why not try to stay with the same terminology?:  "Both types of flow
control are between the endpoints of a single hop, and not over the
entire end-to-end path."
