That is literally not what the paper says. How are you the supremeautismo if you have zero autism? I am familiar with Blanchard's work and the chance of being gay is not that dramatic. Blanchard found that there was a 33% increased chance that a younger brother is gay compared to the previous brother. Let's say that a first-born male would be gay at a rate of 2% for this example. So if you are the nth brother in your family you would have a 100*0.02*(1.33)^(n-1) percent chance of being gay. If you were the fourth brother you would have an 4.7% chance of being gay, in other words 1 out of a group of 20 fourth brothers is gay.
