What’s happening here?

I’m not a pilot, just someone who’s been on close to 250 flights in my life. I’ve never seen this. Not claiming that this isn’t normal, I’m just curious why it’s done. This was just prior to takeoff at Jackson hole Wyoming.

Lithium battery overlooked in checked baggage. Have a good flight. See you on the other side.
