I know that was Kaido but you can't say he is in wano for sure. Law was engaging in combat with a Navy admiral and one of the strongest Sichibukai shown, so what can you expect. Besides, it has been hinted that Luffy and Law are almost equal in power level. Well, with gear 4 Luffy might have upped him but Gear 4 has time limit so well..

And about Kaido, sure he he's much more mad than before..and with that he is dangerous. But surely you can't say that he will come and hang around in Wano without any ulterior motive. Maybe when he learns that Luffy and his gang are heading there, he will surely be on his way. For now, the wano gang said they are infiltrating..so, they will try to hide their presence as much as possible and with Luffy not with them they are likely to remain incognito. I never said they are to engage in combat with Kaido himself. And even if their disguises fail with zoro, Law and the other samurais I bet they can hold their own against at least one calamity and his underlinings.
