The basic premise is 'does the act of deciding require for habits to be called upon to make the decision?'
That is, do you need to call upon habits in order to make a decision?
Rather than just choosing an act, you get in touch with the habit that would cause such an act.
This would contrast with being entirely in the moment when deciding, without relying on habits.
One way to understand this is to ask yourself to make a decision, then, see if you rely on your habits to truly make that decision...
