You got it. That's the thing that others don't get especially in Facebook comments that it's just good for them if Casimero will trashtalk because he is selling the fight or just being arrogant. There's a risk on what he's doing.
It's ok to be comfortable that he can beat either Donaire and Inoue but crossing the lines thru trash talk and then he will lose later on will result in his trash talk not being an effective tool for marketing on his future fight.
