You don’t get it. Sengoku thinks that Ochoku is good enough to be grouped with Shiki, but not good enough to be grouped with the Yonko.
Yonko > Shiki
Yonko > Shiki
Literally doesn’t change canon chapter 0 having Shiki ~ Roger and Garp and Sengoku teaming up to stop Shiki
Shiki > yonko is literally canon lmao
