According the the video this thread is about, the glass has a coating of plastic over it, likely to help with impact resistance. This means the outer surface can be scuffed/scratched in ways that cannot be wiped off. This scuffing is described in the video you linked during his first tests. This could be an issue if you get a scuff in front of a camera. Seems like the laminate combo of plastic and glass is very resistant to breaking though, which is great. Maybe that tradeoff is worth it.
