You right about that, the umpire should not of let the play run out then call LBR.when the pitcher raised her arm to simulate a throw, the LBR was immediately "off" and the runner may choose either direction. However, if the pitcher lowered her hand and did not make a throw, it is again "in effect" at which time the runner must advance directly to one base or the other. My biggest issue would be that the LBR is a "dead ball out" It should have been called immediately when the baserunner changed directions.... right?
