Well, In my opinion, this and many other similar issues caused by the "bright idea" to split the road in some places. 
Splits looks like turns for navigation system. In fact if you just going straight on this road, you will be constantly bombarded by fake turn, when you will be told to change lane and turn somewhere while you actually going straight.
For the same reason turn left on double-split road looks like going through 3 separate intersections, which might have higher penalty then u-turn and cross non-sense.
