In general, true.
It doesn’t sound as though this service is conventional proxying,
though. It sounds like they’re dynamically rewriting web pages to reduce
the number of TCP/IP round trips. Since a round trip via a satellite
takes about half a second, there’s a lot of scope for speeding things
up.
I’ve been involved with a similar problem, with a site with lots of
small graphics hosted in the UK, and customers in Australia. Putting the
graphics on a content delivery network with Australian servers knocked
five seconds off page load time. Fedora netem was very useful in
demonstrating the effect of the ~0.3s round trip time.
