ranger's companion talents: "companion" vs. "self"

[Evil Twin]

There are a number of ranger's talents which are ambigous, take this one for example (straight from the Wiki):
 

Vicious Companion General Group Ranger-specific Activation passive Changes Influenced Ability Animal Companion Changes x 1.2 damage

Trains the ranger's animal companion in vicious tactics, causing it to deal more damage with each hit.

 

But later, in the "formal" part of the description (right click in-game) the 20% more damage refers to "self".

So, who really is making 20% more damage, the companion or the ranger?

Companion talents will be on your companion not you, AFAIR.
