Haste bonus

[Black Wolf]

Vampiric Mist from Bestiary 2 has an ability that reads:

Blood Overdose (Su) When a vampiric mist gorges on
blood to an extent that it gains temporary hit points,
it moves much more quickly. It gains a +2 haste bonus
to its Armor Class and on Reflex saves, and can take one
additional move action each round.

Is this supposed to be a Dodge bonus? Or is haste bonus some kind of new bonus?

[Tarlane]

I am guessing that this is supposed to be a dodge bonus, since that is what the spell haste gives. There wouldn't really be any cause to create a new bonus type for this since dodge bonuses from different sources stack anyway.

As dodge bonus type always stacks, my guess is they put in that language to clarify that the improvement is from a Haste effect so that it will not stack with actual haste spell. (mostly directed at the extra attack) but the AC portion is really a dodge bonus.
