It's definitely the latter and not the questionable win because he totally deserved that win, it's just that his opponent, Ryo Akaho, faked everything and that the back of his head is hurting after receiving a punch from Casimero. Fortunately, IIRC, Casimero and his team did reviewed it together with the rest of KBM and found out that Akaho was just a good actor and was afraid to take the defeat into his career. Gladly, all that is behind now and Casimero is steadily winning and upping his ranking.
Yeah, after that review the organization gives credit to Casimero and his camp.
With that good achievement in this new division, he's climbing a little and with more to come the chance of making his way
as a good contender for the belt, maybe good timing if Inoue will win against Fulton and decide to stay, though still depends
from how the camps will negotiate and how the deal will be closed.
