ASA Change? Or Typo?

[Dakota]

Having no inside information on the proceedings of the ASA rule change committee over the years, but based on rules clinics, etc., it is my belief the change was deliberate (i.e. allowing the runner to return during the dead ball). In addition, a change was made to prevent the runner from returning after the runner had advanced on the base awards.

As to the remaining sentence regarding the defensive action, it would seem you may have discovered yet another editorial change needed in the ASA book. Not exactly earth-shaking news, but perhaps it will be noticed by the "clean up the book" process that is rumored to be underway.
