The announcer addressed this, he said that he footage was not the same but looked similar because of the proximity of the boosters to each other. I think they were just extremely well choreographed. If you watched the side view from the landing pad they landed at almost exactly the same time.

In the on-board footage both landed on the same pad. https://youtu.be/wbSwFU6tY1c?t=37m53s

Ah you're right. If you go back a few seconds you can see its using different camera angles. I'm guessing they just accidentally switched both to the same booster for the landing shot.

Its an easy mistake to make. Given they seem to use Livestream i am going to go out on a limb that they also use Livestream Studio....great software but when you are setting up PiP and copy and paste it is incredibly easy to forget to change the input source on the second frame.
