I bet it is a bus driver they just said they were on lay over doing paperwork. From the videos you can see more than one bus sitting there. Maybe it was a driver from another bus joining another bus driver in his bus, he enters the bus and maybe stands at the top step handing the other driver a cup of coffee or something.

At that time, I think it would be the driver's first run of the day.
