What's the purpose of "Replay" "Auto" icons in Replay window?

What's the purpose of the "Replay" "Auto" icons located in the bottom right side of a replay window? (click to enlarge)


If I click on "Replay" it toggles to "Follow" and then "Free"
If I click on "Auto" it toggles to "Manual"
But nothing changes
So what is its purpose?

I think this is to change the camera perspective.

If this does not have any effect, then you are watching a replay which does not have different camera tracks.

Thanks, that makes sense
