 Absolutely right.  The strike zone is not a flat plane like a pane of glass.  It is a five-sided, 3-D area determined 
not by where in the box the batter stands, but by the area over the five-sided slab of whitened rubber we refer to as "home plate."
Pitches often come in as inside, then break over what is known as the "back corner," which is located 8 and 1/2 inches to the rear of the front edge of the plate.
