No, the chapter was mostly based off where Luffy had landed. Kuma supposedly is in control of where he sends people off to so I could only assume he send them all to the same island. Although Zoro is in serious bad shape so I have no clue where Kuma would send him. It was pretty apparent though that Kuma is a mutual friend of the Straw Hats though.
And expect Luffy to get some kind of powerup coming from this island; whether, through self training or learning something from the island. My main train of thought behind this is because the past few chapters showed how helpless he is when it comes to protecting his Nakama from PX-1 and Admiral Kizaru. The last time Luffy got a powerup was after he had met Aokji for the first time.
