Coincidence ?

When Alibabab return in the real world, he fall directly on Judal (accordig to the second image). 

I had already found this strange before but the dark continent is really huge so the fact that Aibaba and Judal cross so easily is really strange.

In this chapter , we learn that Alibaba is in reality reappeared in the real world just in front of Judal … while he was returning from the “dimension where Ill Ilah was sealed in". 

A odd coincidence, no ? Is this because Judal has a very close link to Ill Ilah or is it because Judal IS Ill Ilah?
