There's an engaging account of this incident in an American Airlines training seminar that's now on Youtube - it's even more dramatic than your summary suggests: [VIDEO] (Incidentally, this is the video series that includes the famous "Children of Magenta" lecture, which is a must-watch for anyone who designs or thinks about how to use a system with multiple levels of abstraction: [LINK] )

MCAS is not a stick pusher -- and that's the crux of the problem. A stick pusher would essentially adjust the elevator to pitch the plane down. MCAS trims the stabilizer. At full stabilizer travel you may not have sufficient elevator authority to overcome the downward pitch. Put another way, you can counteract the stick pusher by pulling back (although this may take a strong pilot). If you don't catch MCAS doing something stupid and the plane ends up fully trimmed down you cannot counteract this by pulling back. Here's some other examples of what happens when the stabilizer is trimmed without the pilot knowing. Sadly Capt. VanderBurgh died a couple years ago. Had he not it would have been fascinating to see his take on the Lion Air wreck. [VIDEO] And here's a quick overview of how the stabilizer functions in a 737: [LINK]
