Framing pitches

In many places I have read about the importance of watching the pitch all the way into the mitt, and "seeing the pitch again" in the mind's eye before making a call. I was surprised to find this approach advocated, as it seems to suggest that the catcher's framing is indeed likely to be an important part of the umpire's decision-making process.

I don't see why you find this surprising. Do you think it would be better to call the pitch BEFORE it reaches the catcher's mitt?
