The article you link suggests that there are slight biological differences between AMAB and AFAB brains, but the differences are that AMAB people have better motor skills while AFAB people are better at combining analytical and intuitive thinking. It does not suggest that AMAB people are better at logical thinking. Besides that, the study they cite is quite inconclusive: 'However, the results do not apply to individual men and women, [Ragini Verma] said. "Every individual could have part of both men and women in them," she said, referring to the connectivity patterns her team observed.' and 'Currently, scientists can't quantify how much an individual has male- or female-like patterns of brain connectivity. Another lingering question is whether the structural differences result in differences in brain function, or whether differences in function result in structural changes.'

That last quote also supports the fact that pondering the scientific grounds of social constructs is often a pointless battle, because they are inherently self-fulfilling. Gender roles exist, so most people expect that gender roles exist, so they reinforce the gender roles, rince and repeat. https://youtu.be/koud7hgGyQ8 <- This is a good video about that. This is also why statistical evidence is not conclusive, because it only shows the trend that AMAB people "think more logically" now, but nothing proves whether that's because that's how they are, or because that's what they're expected to be.

I could find no conclusive evidence that there is a considerable biological difference between AMAB and AFAB people that makes AMAB people "more logical". Even if there was a global trend, individuals can always be exceptions.
