@nophead:
(As you know) tower makes sure that a few layers of an island are built right after each other instead of many switches between the islands. For this object it is where the horizontal teardrop shaped holes are.
Most of the gain in terms of reduction of stringing is because of the combing feature though. Without it, it used to jump from one place to another crossing the boundary of the object many times. Now it seems a path along the interior and usually takes a short path to a place it cannot reach without crossing the outside boundary.
