Not entirely as Matthew said. It satisfies those applications where the standard prescribes that the hanger shall be of a type that resists upward movement only. Restraint (as described in 13) is a lesser form of lateral bracing and is to be installed at the specified intervals and ends of lines. And within 2' of a hanger that resists upward movement if I recall correctly (don't have 13 with me - riding shotgun with my 15-year old daughter at the moment).
