Maybe he didn't have the samples tested because she told Hulbert what he'd find. In any case, what does the number matter? A hooker can still be raped. The alleged victim and the alleged perp both have credibility problems. I'd still send it to a jury.
If Hulbert knew who those two samples belonged to, he was required by law to tell the defense. He hasn't.
And it matters because a policeman got on the stand and swore under oath that she hadn't been with anybody except Kobe.
I tell you this: so far, Pam Mackey has been "more right" than that prosecutor.
