It's possible. I'm speaking on hearsay, not what I observed, but I do find the fact that they "teach" both Kung Fu and Karate odd, to say the least. It's not hard for somebody to fake styles to the layperson if they have X amount of experience in something. My old sifu showed me ads in trade magazines that said things like: "TaeKwonDo teachers! Want to increase your income with Kung Fu classes? Send away for a course now!"
