I would almost guarantee that the Authentication program doesn't include the authenticity of the card particularly in the case of BAS and the older PSA Blue flips. First, with graded cards they are only authenticating that the slab is real and hasn't been tampered with. Secondly, that would open them up a whole host of liability. A good example would be the card below. There is absolutely no way eBay would be dumb enough to guarantee the authenticity of the card named on the flip with cards like this below in the market.
