From the article we know they are not checksumming all hardware agains the original device as they were able to change some assemblies. Really what this means is the sensor assembly moved into the screen assembly [1] and the youtuber didn't investigate further. If the sensor changes this breaks the chain of trust for FaceID [2] and you want the system to stop working because someone, for good or bad, is tampering with it.

Note, the screen and sensor assembly might not necessarily be bound together.
