If that doesn't clear it up, the tl;Dr of that says "EIA *or* PCR" for screening, not "OMGPCRONRY".
If the screen is negative, you are not required to test for RNA.
I can see the confusion because of how it's written, but it basically says "these tests are required, and here's the tests you can do".
The SOP for each lab varies, but it generally goes "do the 1/2 Ab and if it's positive, confirm with PCR".
What I'm confused about is what your issue is. I support gay donors. All I've been doing is having to justify statement after statement while you try to hole-punch. No, I don't have sympathy for your plight as a gay donor when people like me, regardless of sexuality, are deferred permanently just because of where you were raised.
Be happy there's even an option to test for HIV.
They don't even do prion testing for BSE.
