Per RAW, does knowing Assassin’s Stance allow for feats that have “sneak attack” as a prerrequisite?

I’ve read that both Craven and Staggering Strike are very good feats for a Sneak Attack oriented swordsage, however, per RAW, I don’t think knowing Assassin’s Stance would accomplish the prerrequisite of being able to make sneak attacks, since it’s more of an "added" ability rather than a "natural" ability like, for example, the Rogue has. So, as the title says, would RAW allow that? It could easily be houseruled, however my DM is already giving me the stink eye by multiclassing into Swordsage.
