This is how I see it too. And the risk is actual death of the person being embraced, that's why they say it's risky to use.I will say that I believe the novel describes the first embrace as the way the Vampire Queen keeps the bloodline pure
Because it passes down all the mothers genes which is why Bai Ji is completely identical to Lilias
So regardless of gender it should turn them female as well as make them look like the Queen
