The iPhone X has raise to wake, and also wakes if you look at it like you want to use it. So he's arguing that you don't have to press any power button for the display and Face ID to activate. Which is great if you just want to check the lock screen, but you would still need to physically swipe up to the home screen to use the phone. On the Note 8, we have AOD to check the status info that is also in the lock screen.
Other than that, if you are going to physically pick up any phone. Pressing a power or home button is not really an extra step to turn on the display. But it makes some sense with the iPhone when it's docked or lying on a table, because of the lack of AOD.
Also, with the Note 8, you can always use the "Okay Google" or "Hi Bixby" command to turn on the display without touching it. Would there be an actual reason to, without wanting something done? None that I can see.
