Not the original commenter, but I would guess that the goal would be to reflect the population. Women are about 50% of the population, so assuming all things created equal, they should be about 50% of any other population, like those with a specific job title.

If you’re going to compare to the US or wherever, first ask yourself if that place was mentioned in the comment you’re replying to. If not, it’s whataboutism.
