I don't have a problem with doing repetitive drills, or "my aiki brain doesn't do sequence." (I quite agree with that actually.) I would add "my aiki body doesn't execute smartly planned fine motor skills." Humans can do such behaviors so that we can build cool tools, and communicate with language, not so that we can do budo.
The coffee-cup demo exists just to show you what "intent" means. Then, 6-direction training exists just to get you to use intent in a meaningful way (strengthening the body as you go)-- it's a way which doesn't depend on plans or waza.
There's no sequencing or pre-planned actions in "appropriate fitting." So intent is indeed useful for sequence-free martial behavior.
In my belief, truly appropriate fitting is a function of mastery on the second or third level, which can't be reached without exceeding the first. Unfortunately, that involves making one's aiki body execute smartly planned fine motor skills.
That's only my belief, though. Regarding the coffee cup, Alan Watts said the forest creates the bug. So if you find yourself reaching for a cup of coffee, it's because you're conditioned by your environment. Maybe you made the decision, maybe not. Maybe to some degree.
