Legend
As you say. Because of abstraction, I don't mind a bit of hockey button sludge. The one-to-one relationship between player and character decisions is not important to me, or to the definition of association.
1) Hockey players do not deploy "hockey skill sludge button" or anything in the same universe of that level of zoom. They orient themselves toward the resolution of micro-processes (something as simple as taking the correct angle of pursuit or maintaining their back-checking integrity to having their head on a swivel in traffic) that facilitate the success or the failure of the greater, more complex system (the game).
2) Hockey players are not aware of any "hockey skill sludge button" and they aren't aware of any fortune resolution tied to it (because it doesn't exist outside of TTRPG mechanics).
3) Therefore, hockey players and the TTRPG players who are "having their characters play hockey" are not sharing a similar decision-making process nor a decision-making portfolio.
4) Consequently, if 3 is true, then they can't possibly be making the same decisions for the same reasons.
Hence, lacking association in the way that you are attributing is necessary to avoid the dissociative label (but attributing it nonetheless).
