It will certainly do that. Previous attempts at this (the Olympics did genetic tests from the 1960's through the 1990's, other organizations have done similar tests into the present) always did wind up discovering cis women raised as women from birth, with female presenting genitalia, who failed whatever genetic tests they were doing. At least one of these women even went on to give birth to a live human baby! You would think that would prove that they actually were a woman, but their medals were still kept from them. They were still driven from the sport, branded as cheaters, etc. Because someone who was so much better than the rest can't really be a woman, they have to be cheating somehow, they have to be a man.

In fact, I'm not aware of any genetic testing program ever catching any deliberate cheating, only people who were raised from birth as women. The very first example of this, (1), Dora/Heinrich Ratjen (2) seems to have been an intersex person who was definitely raised as a girl from birth who was a bit confused about what their body was doing. But all the way back in the 1950's when their 1936 Olympics became a big deal, we have lurid tales in the English language media of deliberate cheating that don't seem to have been supported by anything that Ratjen ever did.

I wouldn't call it cheating. But I have no trouble drawing lines that exclude some people, if that levels the field for a bigger group. In this case the female olympics would soon be known as the intersex olympics given the selection pressure. I can understand the decision to make the competiton more interesting by barring intersex people. No need to frame it as cheating though.

Since we don't actually do genetic tests at birth, this would only ocurr in the context of national qualifying, think about what the experience of someone who trains to be good enough to qualify for the Olympics, then gets this test and is told, "Sorry, you aren't really a woman. Too bad. No Olympics for you. Sorry you wasted all those years training."

How else should the person who just got that information interpret it except... Sorry, you're not really deserving, even though your score qualifies you. And what do call someone who has a score that qualifies but doesn't get to go?

And there are far more of people with this experience than the experience of being born and treated by society as a man and becoming an Olympic athlete as a woman.
