That is my guess (that he winds up with another flock). Guineas hate to be alone so his top priority would be to find a flock to join. Hopefully he makes it that far. 
 
I will add, though, to not be surprised if your keets also go up the hill. Where I live is flat and for the first few months after they started free ranging, my guineas would fly up on my roof several times a day, I think to memorize the landscape and layout. I would expect them to use hilltops in the same way.
