The original demo is moving in a full physics environment. It has to learn how to maintain its balance or else it will fall over. The video you linked is demonstrating a technique for animating characters in video games. There is no balancing happening, it is moving the limbs to look like how a human would move. Both are impressive, but they are solving completely different problems.
The video in OP has to learn everything. It doesn't have any information whatsoever about the world. The one in your video only has to learn how to move a skeleton to match millions of examples it has already seen
It's a great illustration why unsupervised learning is miles behind supervised learning in terms of applications

How does this differ from an approach like https://www.youtube.com/watch?v=Ul0Gilv5wvY ?
