There are huge variations in styles of Silat. Sometimes styles can be similar if they're from the same general region, but even then they may not be. Saying Silat is about as broad as saying Kung Fu, or even Martial Arts in general.
That style seems to be mixed with Chinese Kuntao, which isn't necessarily a bad thing, imo. (I practice Kuntao Silat myself) Seems pretty neat, I think you should check out a few classes and see how you like it.
Check out this link to Martial Talk. A guy here talks about White Crane Silat and what styles of Silat go into it.
