Actually, the instruction (which appears to be from the driver's license book) does look to be relevant. It says to back into the lane closest to you for the direction you'll be going. The picture shows what appears to be a four-lane road. The silver car backed through the closest lane and into the further lane.
Whether the DL manual constitutes binding authority is another matter, but at the least, I'd think it persuasive in assigning relative fault.

“Back Slowly into the lane closes to you for the direction you will be going. Don’t back any further than you have to.”
Could it fall under changing lanes
Okc manicipal code
§ 32-191. - Changing lanes.
(a)
Whenever any roadway has been divided into two or more clearly marked lanes for traffic, in addition to all other rules consistent herewith a vehicle shall be driven as nearly as practical entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety and has signaled for a change of course.
