thats a valid criticism of normal polling, which is attempting to forecast the voting intention. they dont know of changes or their impact until after post analysis with the result. as exit polls are a snapshot of voting behavior that has occurred, its inherently more accurate, should smooth out demographic variations and reflect changes well.
If you read what occurs with the exit poll, and compare it to what goes on with standard polling, then you can really appreciate why the former is far more accurate than the latter. I still think that certain circumstances will throw up flaws with their methodology and models, however.
