I don’t disagree with your overarching point, but it can’t be quite that simple, if it works as advertised. In order for it to send a name with the photo, the passenger would have to scan some sort of documentation to provide their name, which would defeat the purpose of “your face is your boarding pass”.

It seems more likely that the CBP system compares against passenger manifests of upcoming flights. Which isn’t necessarily more intrusive, but it is a bit less straightforward than a simple yes/no query.
