Snake Bite filiger set

Question: Does the Snakebite "+4 to your DC of Poison attacks" add to the DC of the various Alchemist Poison vials? Or is it just for Rogue Assassin Melee Poison Attacks and suchlike.

Sadly it appears that it does not affect the DC of Multivial Poison. (At least, not according to the tooltip)
