That's diffused vs. focused modes of thinking. I see it like a river entering a new landscape. In the focused mode the landscape has defined hills and valleys so the river has little choice where to flow. The Diffused mode is like a very flat landscape, not much is going on there so the water can access pretty much any part of it or keep changing the way it flows randomly connecting different points.
