To make it simple, this recipe shows just one case of a start animation: the 180 degrees turn. You may require more start animations (-90 and +90 degrees turn or even -45, +45, -270, and +270 turns). You may also need to add a 180 degree turn transition from walking/running to make the character react to the input faster. In such a case, you may need to use Animation Curves to determine the walk/run position (LeftPassing, RightPassing, LeftExtreme, RightExtreme) and play an appropriate turn animation accordingly (starting with the LeftPassing, RightPassing, LeftExtreme, or RightExtreme pose).
