I think it would mean that changing a “default” response requires deliberate effort to generate the neural pathways that let you behave otherwise. There’s an illusion of choice in your consciousness, but the energy required to make deliberate choices is wasteful, so if you turn left at some corner 100 times, you won’t need to exert much energy to decide to turn left, even though you could turn right every time and probably needed to use your deliberative consciousness to specifically choose to turn left the first time.

It says that perception is not conscious. So what we experience as our conscious perception is accessing the most recent memories, which could reasonably be used to actively choose a course of action.

That would make sense with theories of mastery, where early stages of doing a new task (walking, riding a bike) require our full focus, evolving to an ability to do the task under normal circumstances, then to negotiate common obstacles, then to deal with novel obstacles as they occur. The conscious effort discovers and develops solutions that our unconscious can use in the future, so when you get bumped while walking, your unconscious corrects, while your conscious mind continues to work on other things.
