Yes those are their actual names, after the backlash they never appeared in published comic(these are from sneak peaks at a then unreleased new New Warriors series) apparently their origin involved inhaling 'internet gas'
On the one hand, non-binary people don't owe anyone androgyny: my own non-binary OC reads as pretty fem-presenting outside of xyr own fictional culture, but goes by xe/xem, You Can Just Do That. So if these two characters were real people, we hopefully wouldn't be complaining about them not looking "enby enough."
On the other hand… It really does feel in context like they just took a stock woman and man, gave them both short hair, and gave the woman the boy color and the man the girl color, and called it a day. It feels like a pretty cringe forced insertion of the gender binary, I guess.
