My point was more that being immersed in porn-star culture means she's accustomed to the notion of people having different names, and when she's confronted with a tall busty Amazon who she thinks is named 'Yuki', combined with what Somebloke said about unconscious self-projection, it's not out of the question that she just instinctively assumed her target had changed her name to Yuki.
If this was QC, though, I'd heartily endorse the grown in a vat theory.
