The Jep plate probbaly gives the best clue.
FWIW, I think it's rather misleading. The AIM makes it very clear that you can pick your reversal when there's a barb symbol like that on the FAA chart. Jepp picks one of them (the 45 degree PT) and doesn't appear to offer guidance that alternatives are available.
Nevertheless, I agree with your description of flying the procedure, though technically it's a "racetrack reversal", not a "hold".
