Very likely they're turning the prop to pull oil from the bottom cylinders, before starting the engine.

Pulling the prop through to assure oil is spread to the top of the engine. The upper cylinders of a radial engine would drain when shutdown, so a crew would rotate the prop several revolutions to get some oil back up. Magnetos off so it would not start, and care to assure that cylinder compression did not cause the prop to "kick" while anything was in the way.
