Most of the top-tier publications actually do make a point of hiring people with subject-specific expertise. I first noticed this when The New York Times' lead medical correspondent was identified as Lawrence K. Altman M.D., because he really had earned a medical degree before heading into journalism.
In my own journalistic travels, I've worked alongside legal reporters who graduated from Harvard Law School, Wall Street reporters who earned certification as Chartered Financial Analysts, tech reporters who majored in computer science at Stanford, etc. That doesn't make them instantly right about everything. But it does mean they have the training to parse conflicting claims.
I'm not sure about the credentials of the specific Bloomberg reporters on this one. But Bloomberg does have budget and resources to hire subject experts to report on complex subjects.
