It’s possible (although not the most natural reading) to interpret
girls routinely outperform boys in every subject, including math and science
as something along the lines of “boys do not consistently top the class in any subject; there is no subject in which it is at all unusual for a girl to be at the top of her class”.
My priors were that, for similar levels of maturity girls collectively do better on classwork and boys collectively do better on tests, that girls mature faster at young ages, and that the bulk of grades come from classwork in younger grades. So I would expect girls collectively to be routinely outperforming boys collectively at the 5th grade level. The statement that there are no differences between girls and boys thus struck me out of left field- the only explanation I could come up with was sex sensitivity (if girls are doing worse, there are differences, if boys are doing worse, there are no differences).
Thinking about it again, I came up with another interpretation: the “these” in front of “boys and girls” is referring to the bright ones. So bright girls routinely outperform average boys, just like bright boys outperform average boys. But that seems like a sloppy way to compare distribution tails.

That is a plausible interpretation.
