Well...you're seeing the linking fist sequence which is a popular intermediate form.
I don't think I've ever seen the form performed in this way.
The movements themselves have some good "snap" to them, but they are very tight. I don't think there is a full extension of any movement during the entire performance.
I believe that this is a guy who specializes in delivering power from a close range - as his form seems to suggest.
Here's more of a 'wushu' version of the form:
