Not necessarily. Of course it has to be defined what will happen when an allied unit with -disablehelp attacks an already Nightmared unit. But since it's the attacking player's fault, Nightmare should be passed to him even if he has -disablehelp on.
If the check for -disablehelp is only done when Atropos casts Nightmare (and not when the dummy unit which "passes" Nightmare casts it), it will cause the behaviour I mentioned above.
