The first exchange in that video which they show twice once fast and once a little slower, is a failer. Anton, the guy on the right, probes with his sword on his opponents left (Antons right). His opponent strikes at Anton’s sword to fend it away (parry),but somewhat overcommits. Anton’s already in mid-air and switches over to the other side avoiding contact with the blades, and hits the guy real hard on his right (Anton’s left).
