in actually it is true that you continue learning even after you have practiced or preformed an event. To be basic and vague, it has to do with reflex from the cerebellum of the brain in which it is monitor fluxuations of fine tactile movement. Needless to say, even after your practice period, your brain is continusly rewriteing complex reflexes in turn which allows more autonomius responses when playing. Thats why sometimes when you take a brake and come back to something, you perform it better.
