BR Passing Obstructed Runner

[jmkupka]

R1 is on 2B with one out. B2 hits a long fly ball to right center. R2, thinking there are two outs, begins to advance toward 3B as soon as the ball is hit. 3B coach shouts to R1 to return to 2B and tag up. R1 is obstructed by F6 as she is moving back toward 2B, F8 and F9 fail to catch the ball and then R1 is passed by B2 between 2B and 3B.

Our interpreter rules that the OBS protects the BR from being called out.

My thought was, this should be ruled differently from the standard "R1 is rounding 3b, is obstructed, and is then passed by BR", since R1 is headed back to 2B to correct a running error.

Any thoughts?
