Rule Question and Mechanics Question

[Stair-Climber]

Would like answers for National Federation and ASA.

Rule Question: B/R hits to outfield. B/R rounds first and stops several feet from 1B and stays there with hands on knees and facing pitcher in circle. Ball comes into pitcher (in circle) from outfield. As soon as pitcher receives ball in circle, pitcher quickly turns toward B/R and just stares at her (she neither throws to F3 nor threatens a throw--just stares at B/R). B/R doesn't move, trying to get pitcher to play on her. Has B/R violated look-back rule or is pitcher playing on B/R by turning toward her and staring her down?

Mechanics Question: On a missed swipe tag, no call should be made indicating there is no out--correct? In other words, on a missed swipe tag, umpire should not signal save (the no call means that the tag was missed and not out) and should only make an out call if tag is made--correct? Or when swipe tag is missed and runner makes it to base, then should a safe call be made?
