I'd probably just call it a case of a male name following female linguistic rules - i.e. an exception. The supposed gender of the name isn't necessarily evidence of the actual person's gender. For example, in Italian (A latin-based language) the name Andrea is a male name. But following the typical rules of word gender in the language(-a typically denotes a feminine word while -o typically denotes masculine words), it should be female. I would give more examples but that's all I can think of off the top of my head.

I'd hardly consider it relevant unless they plan to use it as a plot device/ character development later on.
