The part of my post which you quoted refers to account sharing with two account-sharing persons' gender and birthdate being different from one another. No mention of name in that section.

To go into names and sex/gender:

Many names are used in ways that gender may be less than clear. A variety of names in South/Central Asia that are considered "female" there (as well as perhaps "male") are considered "male"-only in SW Asia. In other cultural arrangements, there are names like Andrea which are used by males and females. Then there is also the sex/gender-change(d) community, which many more may consider awkward but really is just a natural continuation of what has been around for millenia.
