On the contrary, I would argue that conscious attention is only focused on one of those subroutines at a time. When the ball is in play you focus in it, and everything from your posture to racket handling fades into the background as a subconscious routine. When you make a handling mistake or want to improve something like posture, your focus shifts to that; you attend to it with your attention, and then you focus on something else.
In either case, with working memory for example, conscious contents are limited to at most a basket of 6-7 chunks. This number is very small compared to the incredible parallelism of the unconscious mind.
