Like many other trans, she tries to downplay the 'essentialism' of the respective dimorphic anatomies of men and women. Bones, reproductive organs, etc. Features she won't be able to change without considerable effort and expenditure on her end(and even then, never completely and without lifelong complications).

So instead she opts for focusing on the much more easily attainable gender validation from the "chemicals" in her body; The replacement hormones she receives. And perhaps she factors in the so-called science of trans brains that she may believe she is subject to.

For that reason, she claims that her biological makeup matches that of a male's. And sure, while some features(voice, body hair, fat structure and distribution) may change to be more 'male-like' from HRT, the most integral aspects of her won't. She'll instead mainly irreparably harm her body the longer she carries on with replacement, precisely because her "synthesis" is so intrinsically female rather than male.
