They do have a connection, they are both. In the same place and Luffy told Sommers to remember Zoro's name.
There is no evidence that they are in the same place, apparently Sommers does not appear in the chapter, which strengthens the possibility that he might be dead, and according to the clue Redon gave, Zoro is doing something, which means he might not be in the same place right now.
 
Zoro fighting Imu here is highly unlikely imo. Oda easily could’ve had Zoro catch a ride on Loki’s back alongside Luffy and Ragnir

Instead he placed emphasis on Zoro staying behind and protecting the village. So I think you’re right either new Knights pull up and Zoro has to defend the giants or Sommers gets back up and Zoro has to cook him
Imo Zoro completed his job in freeing brogy and dorry and will now after this chapter go and leave it to them and ussop to protect everyone.

Usopp isn’t there yet and I don’t think Zoro would just up and leave right after Luffy left the village to Zoro

But then maybe he would I won’t claim that I know how everything will go
