The majority of Yuusei's strategy when he had to go non-lethal back in Shabon was to rear up on his hind legs and bring his foreclaws - along with the force of his body weight - down on his opponent to pin them and let whatever needed to happen next happen. It's this that he attempts when he emerges from the shadows, allowing the force of his initial forward movement to keep him going as he tries to shove his foreclaws into the remaining two technicians' backs and knock them to the floor.

Should he succeed here, he'll plant his foreclaws onto the two and outright lower himself onto them to keep them from escaping - and, more importantly, to get their visors within arms-reach to pluck them off.
