I would have to say, there was enough CLF in there for a CLF disciple to distinguish. To an outsider of CLF, you would only see what's familiar to YOU.
I am one against traditional styles taking on a KICKBOXING type appearance, but in defense of this video, I saw a few Kwa Choy Chop Choy strikes by the guy in black, both individuals used the spinning back fist as well as other CLF techniques.
Remember, fighting is INDIVIDUALISTIC, which means the fighter has to learn to make the style work for them.
