As far as I can tell, Richard Love's interpretation is mostly correct (which is why I dislike RAW personnal wards and House Rule them instead).
IIRC, there are at least 2 exemples of such Personnal Wards against Humans. One is a verditius from an antagonist covenant (the one with Drums as casting tools), I can't remember from which book. He uses it before going into Battle
The other is in Magi of Hermes. One maga (a tytalus) has a twin sister, and both have an item enchanted with such a Ward. However, I may be wrong, but I believe that is doesn't work against missile weapons, which, while it contradicts the RAW on Wards, make things a lot simpler.
As per the OP, I believe the answer is yes, the reason being here (And I can't believe this hasn't garnered any reaction, given how huge this is IMO):

If this works for ReCo, I can't see any reason why it wouldn't work for PeVi.
