He's really slow in the video. I use Swift key (not swiping, just typing) and I'm many times faster than that. Can't see how an expert would be faster either, the gestures simply take longer than simply hitting the right spot.
Also Swiftkey is pretty forgiving once you use it more and the predictions become a real time saver.
