The short summary gave me an impression that Big Mom is winning this fight. The full summary shows the damage Kidd-Law have done. Big Mom is going down before Kaido.
Regarding Kidd-Law: No matter how underwhelming Kidd is, he is still having the final attack of the chapter. Same happened at Punk Crash chapter when he got the final attack after Law's anesthesia. He also got a small plot in the chapter before when Killer had to beat Hawkins to free him up for the fight. No matter how you look at it, Kidd has been portrayed as the central figure against Big Mom.
