Agree, same view of the flame of the same booster, indicating it's the same camera on the same booster... the glare shows up in both feeds.

If it were two different cameras we'd see two different landing pads. In the end of the video both feeds are coming down on the northern pad.

Edit: Here's the sat image from december with notes added https://imgur.com/a/u6sLs

They were two feeds from two cameras on the same rocket.

Since they are on the same rocket, you see them land on the same pad.

The rockets have redundant cameras, and through a probable misconfiguration we saw two feeds from two cameras on one rocket.
