Sure, that's pretty clear :). If you want to re-read my post above I wasn't saying that would be as good at game rules and there's a very real limitation as soon as you get away from scripted encounters and into anything more complex.
At the same time consider there may be people, teams and designers who it does work for. Very few things are in absolute and there are places where I've seen tools like this used effectively.
