Does Ivern really free the jungle camps?

So apparently Ivern can free jungle monsters with his passive but if he really freed them why would the jungle items passive that specifically states when you kill a monster still grant the extra exp. What is the meaning of this is it some kind of joke? he is suppose to protect the animals but gets rewarded for killing them that's not right. I think some rewording is in order im sure someone as peaceful as ivern wouldn't harm the creature of the river. what do you guys think about this contradiction?
