It's nice to provide links.
YouTube: Apollo 15 waving flag, about 3 minutes of NASA footage.
My first guess is that the astronaut who passes between camera and flag, simply brushed against the flag. The distance may not seem right, but the lens, or zoom setting, could provide false clues about actual distances.
"Clearly didn't touch it" is your conclusion, apparently unbased on actual measurements. That is certainly not clear to me.

This is only the third you tube video I have watched.
However watching it I came to the conclusion that if you watch all of it, most of the time the flag does not move! And when it does move there is, clearly, influence from an astronaut. Moving the flag or passing close by.
However there are long periods when the flag is filmed yet does not move. Also, during the periods when it does move, the flag, clearly, does not behave in a manner consistent with it being in an atmosphere. i.e. The motion of the flag is damped and it stops moving long before what would be consistent with motion in an atmosphere.
