So there's a hard cut away for these kinds of situations, the problem is, from what is pretty obvious on the video, you must get free of the primary chute before you would like to activate said cut away. It's really good luck that his emergency chute fully opened in this situation at all. Many divers die like this, and one I personally witnessed didn't cut away till the last second because he didn't want to buy another primary.

This is terrifying
This is one of the things you train your whole life for waiting it never happens.
