FWIW, the win rate was -91mbb/g, and so they reported the probability of being equal in skill somewhere between 5% and 10%, hence the "tie". The introduction to the other poker paper on HN now (https://arxiv.org/pdf/1701.01724v1.pdf), by a different team, from Alberta, is rather less gracious and says it was a "huge margin of victory". I think that whatever the interpretation, his video makes it clear he didn't understand any of this.
