These were recorded in the simulator as stated in the article by Christian. However there is a recording mode on the device itself as well, although as I don't have one I don't know the specifics.
I see, thank you. I was watching MKBHD and Brian Tong on YT and they were using extensive actual POV recording:

In those reviews it looks like a mix of screen recording (what the user sees), and you can also record and take pictures from the onboard cameras (headset PoV). Thanks to the passthrough, screen recording will often also capture the room and the users hands.
well now those rooms look totally rendered! :)
The screenshots in the post are likely from the simulator.
There’s a screen record function, the same as the rest of iOS. MKBHD uses it extensively in his review video.
