The study sounds like it is trying to blame the problem on the suffers (the "contagion" of their depression), but the obvious explanation of this is that by hiring from organizations with high stress, you're likely to be hiring perpetrators I think that part of it is that certain policies, procedures, techniques, etc are more likely to exasperate mental health issues than others. If someone is coming from a disfunctional organization they might introduce some of those behaviors to the team, even at a lower level. I worked with an ex faang employee that complained about the stressful culture, while advocating for the policies and tech of that culture.
