From what I've gleaned, the result and match are calculated in that couple of seconds after you confirm your team talk. The 2D engine or text display then display their rendition of the game (which is recalculated when you make any tactical changes or substitutions).
The reason there have been so many gripes with the game since the introduction of the 2D engine is simply because it leaves less to the imagination than the text did (in my opinion, obviously).
It's easier to swallow a mistake that you can't see, except in your mind's eye, if you know what I mean.
