I found a link that offers a VCD covering xing yi chain whip

Why haven't I heard or seen any other information on this set? Is this an authentic xing yi form or do you think it is more of a hybred style? I am just a little skeptical that from my training in china and the US I have never heard of this set, but now there is a newly released VCD on this topic.
