The action does not cause the acting model to gain fatigue, because Anum is gaining the fatigue instead (assuming he is using the Alpha ability rather than dying).
"An Exhausted model may not take an action or make a reaction as long as it is Exhausted" is meant to be comprehensive, and all special abilities that trigger a model taking some kind of action will always be impossible to do if the model is exhausted - it must be either ready or fatigued for an ability like Frenzy to be able to make it take an action.
That's how I've been interpreting it as well. Essentially, instead of Anum being able to attack or take actions, the beast does it's stuff instead (flavor-wise, I see this as him being the "beast master" type, probably beating the beast with an object and driving it into a literal frenzy, which is why I also think there should be a range limit, but that's just me).
