I'd say that the vibrations of the astronaut as he 'bunnyhopped' past caused the flag restarted its pendulum movement- the vibrations were transferred via the compacted regolith.In this case the flag moved at the precise moment at which it would be expected to move in atmosphere if somebody walked past it.
Armstrong and Aldrin tried out several different types of movement on their mission, then reported back to NASA with a number of recommendations Some astronauts used the bunnyhop originally recommended by NASA, others used the 'lope' developed by Aldrin. Finally Jack Schmitt developed a 'toe-push' method, similar to ski-ing, which seems to have been very efficient; unfortunately that was on the last mission.What do you think of what I posted above about the difference in body movements of the astronauts in the two different missions?
