Also he was the one who said that Sanji had a big moment.
YP usually get the chapter by himself one day before we get spoilers, on Monday he probably just get a information of his own provider and share it,probably his provider didn't mentioned the King vs Sanji stuff with means he himself wasn't wrong but he didn't know either the full spoiler.
As someone who now know YP since 5years, he kinda show most time us the spoiler, he is my best provider with Redon until know and it don't change it.
