I didn't see the video, but I still think he looks male from the photos. And unmistakably male.
But a feminine enough male for people to think that there's something to it. When you see Roxy Tickle, you just think nah, perv.
When you see Upton, although he still looks male, you might think that there's something to gender dysphoria that warrants more accommodation.
If there was such a thing as being born in the wrong body, you might think that Upton is further along the line than Tickle, for instance.
It's wrong, on every level, but from my experience, perception is very important. Hence pronouns.
Fortunately, perception changes as soon as they speak.
