The video contained almost no information. Just a clip of a cyclist cutting in front of a Waymo car and then a cut back to the Waymo employee. It doesn't even show how the car responded.
That still doesn't say anything other than "our data includes interactions with cyclists." As far as I can tell, they don't treat cyclists any different than they do other obstacles on the road.
They do, the model specifically marks cyclist, pedestrian and other obstacles as different, and they discuss how they're modeled differently. Furthermore, they have videos talking about their simulation system, and how they create thousands of "variations" of each scenario, with the "obstacle" doing different things.
