There is no doubt that the catcher had to be watching Maddux call the pitches as well. It's not hard to have a simple pitch calling sequence from the dugout. Many teams do that at all different levels.

It would suck as a catcher expecting the curveball you just called and then get a fastball. That is the recipe for past balls galore.
