Somewhat.
How do you think they are organized and then move forward to produce a final product?
Now that I actually have the time to answer this, it looks like Bio Edmonton operates essentially two line organisations, one for each of their main franchises. The only people I see moving between the two are the QA guys. The DLC teams appear to be mostly ad-hoc on a per release basis, so that you have a core design team supported by people "on loan" from different specialised teams within the line organisation (cinematic design, writing etc.), while the main organisation is working on the next iteration in the franchise. Whether the core team is also composed of people in the normal ME/DA line organisation appears to vary.
I lack the information to comment if this was the model adopted for Arrival, or if the addition of a new studio meant that Edmonton only provided strategic oversight, and possibly some writing HR assets for the project. Judging from how pedestrian the cutscenes are, I'd say that at least the cinematic design was either handled by new guys, or whoever was doing it from Edmonton had A) a lot to do B) was phoning it in, anyway.
