Before the bus starts moving, the bus and the skater are both standing still.

When the bus starts moving and pulls away from the bus-stop, the skater stays right where she is.

The people outside on the sidewalk see her standing still, and they see the bus moving out from under her.

The other passengers on the bus see her rolling backwards down the aisle, toward the back of the bus.
