It's an hybrid; it keeps a fairly dense grid system while providing tiny cul-de-sac (which aren't really, since the road starts and ends in different spots), which do have some advantages.
More importantly, in my opinion, it's not a cul-de-sac for pedestrians, which avoids the terrible result of taking the car to go to the supermarket 300m away simply because there's no way to walk from A-to-B.
