Their argument is that if offense clearly gains space or a new line that the defense isn't moving to maintain their LGP but must now establish LGP again. In the case of the video this would mean the player was still establishing their LGP at the point on contact as their 2nd foot was not down.

I don't buy it but I don't have to.

With no intention of commenting on this specific play, that is true. If a defender ceases to be in a guarding position (by the definition of guarding) they must reestablish LGP before they have the rights of movement to maintain it.
