The problem is there may or may not be enough context to the whole situation. Any still picture showing him pointing is compelling, however if you watch the small bits of video in existence,
The Babe didn't stop what he was doing and point definitively and directly to the center field stands
(as is always implied). His arm/hand was waving around seemingly pointing at the other team, and pretty significantly in my mind, it wasn't pointing 'high' enough to be majestically directing attention to way out in center field.
(And yes, I want the 'called shot' to actually be true, but it's a tough sell, unfortunately.)
