I don't mean they look similar. I mean they look like they came from the same video feed. When completing the touchdown, they both seem to land at the same pad -- you can see the flame of the other booster and the pad the other booster is landing at in both videos, except they aren't rotated 180 degrees from one-another because the rest of the landscape is identical. Also, watch the moment when the boosters do their initial burn to slow down from freefall. The flames in both videos look virtually identical.
Here's a few samples: https://imgur.com/a/Xpbu8
Did they acknowledge that the videos weren't actually taken from both rockets during the stream and I just missed it? Or is there some other explanation?
