Yep, Kaido and Orochi were relishing on how they fooled Oden and such before.
Also this one of the best parts of Wano and OP imo, unapologetically brutal, raw, realistic (as in someone facing an unavoidable brutal, horrific execution that was typical of this era in history) and horrifying:
OP felt like a Seinen here honestly.
Also, Kaido really admires and wants to be like the (fictional rather than the real ofc) Samurai, that unwavering, unstoppable code of honour to the very end, to their deaths. Devoted to absolute extreme and completely about honour, being uanfraid of death, sacrifice and such.
