The thing you are saying doesn't even make sense as a criticism of the study. You are complaining about something the study didn't even try to measure (the "why"). The study only tried to measure if there was a difference at all, and whether it was measurable.

As a side note, I recommend meditating on why seeing a female name on the internet upsets you, when you should be well aware that 50% of human beings are female. If players didn't get upset and force females to play under male/neutral names, maybe it wouldn't be as shocking to notice when they don't.
