Saying 315 degrees is mostly just to emphasize we aren't completing a full 360-degree circle around the pylon. Instead you are transitioning smoothly from one pylon to the next, slightly less than a full circle before crossing over to begin the next turn.

You said 315 degrees, I thought it would be more like a 270 degrees turns around each pylon
