I think it sounds helpful, actually. It doesn't necessarily mean that all trans people have brains like that, but it does mean that if your brain fits the pattern, then you're definitely trans. So that could be helpful for people that can't seem to figure it out on their own. Just think of how many people we have on here posting stuff like "I don't know if I'm trans, pls help". They'd have a medical option that could give them a definite answer, instead of having to go to a therapist (potentially for years) to try and sort it all out.
