RAI on Phantom Thief's Broad Education Ability

[DrSwordopolis]

Broad Education:

Broad Education (Ex): A phantom thief’s broad studies with expensive tutors keep her up to speed in both martial and magical knowledge, as well as in her skills. She can select the combat trick, minor magic, and major magic rogue talents as many times as she likes, and she can select the Skill Focus feat as a rogue talent, also as many times as she likes. Finally, she can select a vigilante social talent instead of a rogue talent, except for social grace and vigilante social talents that would require her to be a craftsman or professional. For the purpose of vigilante social talents, a phantom thief does not have a vigilante identity and is always considered to be in her social identity.This ability alters rogue talent.
(Bolding mine)

Is the Phantom Thief supposed to count her rogue levels as vigilante levels for the purpose of selecting social talents, or was it intended that only three Vigilante Social talents were intended to be available/useful?

(Love the archetype, by the way)

[Saethori]

Typical abilities like this usually do treat your class's level as the same as the one you are pulling benefits from, so it would be very reasonable to say that you do, in fact, treat your rogue level as your vigilante level.

RAW, though, you are correct in understanding that there is an extremely limited range of social talents available. This ability is probably in need of errata.
