The most obvious explanation isn't mentioned. More exercise leads to more muscle, which leads to a higher BMI. I cannot access the full text, but this isn't acknowledged in either the Atlantic piece or the abstract. There is no talk about more adipose tissue, less fat-free mass or higher bodyfat. We cannot distinguish between good weight gain and bad weight gain based on BMI changes alone.
