Yes that is Denny in the video.

We were heading to Las Vegas when we received the message my captain confirmed with Ed in dispatch to secure the cockpit. He told me to grab the crash axe and keep it until we are at the gate. If I recall we were 5th or 6th of the last flights to land at ORD that morning. I recall watching N653UA (Star Alliance 763) was our last plane in that morning I snapped a photo from T1 B gates.
