Did anyone notice the Face Guarding/PI that happened during the "Phantom QB Roughing" call?

At 6:11 in the 3rd, Kpassagnon is held while closing in on Rodgers, who throws incomplete from the end zone. An OL hooks him around the shoulder while also clutching and stretching his jersey, altering his momentum and forcing him to the ground. My understanding is not only is that holding, but should have been a safety.
Exactly!

And... I said so when it happened.

(But not nearly as descriptive as you did!)
