To me, it looks fairly close
What I like about the video: it shows smart moves, not violence. They seem to be executed in a very smooth and relaxed way, yet powerful, much like what my understanding of Taiji is. The guy is showing the moves, not hurting the partner, and that shows respect too. At the highest level, all martial arts merge, I think.
I liked the hip "fa-jin", very similar to ZTC's 42 fajin form.
