Seems like bullshit. As someone who's been doing a lot of interviewing recently the ratio of male to female SDE candidates is at least 10:1. If we assume that ability is uniformly distributed there is literally no way to get to a 50:50 split or anywhere close to it without discrimination.
If you believe that ability is uniformly distributed, and you're getting a 10:1 ratio of men to women, 9/10 of the men who apply are unqualified. Men are known to apply to jobs they're not qualified for way more than women do.
I have also been doing a lot of interviewing recently and that number seems about right.
