No, he is just plain wrong.

(discussion regarding the difference between bps and baud as well
as an optimistic compression result (8:1!) deleted for brevity)

Yeah, neat.  But it is even neater to be able to do 18,000 bps without
compression, which is what the Telebit does.  After the error detection 
and synchronization bits are stripped off, the actual data rate is closer 
to 14,600 bps.  Add compression in and you can be back up saturating the 
19.2 kbps link between the modem and the computer.  Of course, this 
requires a clean line.

If one wants to put compression into the formula, 2400 "baud" MNP 
modems can do 4800 bps, as was indicated elsewhere in this newsgroup.
But I think this misrepresents the situation.  (ESPECIALLY on my
compressed batched newsfeed.)

Maybe a :-) would have made my last statement clearer.  (Doesn't
anyone around here have a sense of humor anymore?)
