This is true for catches versus foul balls.
However, baseball doesn't use instant replay for balls and strikes. And balls and strikes suffer from some of the same problems as the catch rule:
1. Is the black part of the strike zone?
2. How much of the ball must cover the edge of the plate?
3. Where, exactly, is the midpoint between your waist and your armpit?
4. What about a crouching batter?
