So that must be it. Either Shao Kahn was indeed stupid enough to create something that would work for any Outworld emperor, and not necessarily himself, or Ermac's bound with him was completely broken once again, most likely by Kotal or somebody loyal to him. Or that bound isn't even canon anymore in this timeline.

Also, I wonder if Jerrod being inside him could be canon too. Maybe he's been Ermac's consciousness all along, but only gains voice when Ermac's not being controled by Shao Kahn. That doesn't even need to be mentioned explicitely in story mode, but it'd be cool if they somehow hinted that at some point.
