If you go to 16:10 on the video you’ll hear a call to relinquish control of the cameras. Due to the classified mission only authorised personnel are allowed to see the data from the second stage, so the commentator would not see any of the usual information. I assume to get the fairing deployment conformation they would have to ask someone which would take a little longer than just looking at the data.
