It's not supposed to.
A better title would be "A general introduction to Nietzsche's life to people who have only heard his name" -- rather than the more promising "Nietzsche’s Eternal Return" which only concerns half a hastily written paragraph in TFA.
That said, it's quite poorly informed in the philosophical aspects (didn't bother to check the biographical ones):
"Scholars still debate what Nietzsche had in mind. A physically stronger being? A spiritual aristocrat? A kind of cyborg?"
Scholars might still debate "what Nietzsche had in mind" with Ubermench, but they don't consider any of the above options (except perhaps "a spiritual aristocrat", and that's still extremely vague).
