Could you possibly point out where you think you've read that in the
text quoted above? In case you just have a particular scenario in mind
where at least a large part of the caches that hold a copy of the
compressed version sooner or later get a request for the uncompressed
version: How about considering a scenario where my suggestion could be
sensible rather than specifically making one up where it is not?

Plus, I obviously listed possible traffic reduction at the server only
as a secondary advantage.
