First things first: I agree with you that what this pitcher did in the video is not a play. Her slight arm lift may have been an effort to adjust her uniform sleeve for all we know.

That said, I still don't understand your point. If the pitcher does something to cause a runner to react, it shouldn't matter if the runner is on a base or in between them. I don't think we need to figure out what movements constitute a play under one circumstance and not the other.

Heck, one could counter-argue that a complete fake throw by the pitcher won't cause a runner on a base to do anything because the runner knows she's not in jeopardy, so that shouldn't be considered a play.
