ASA Double Base - Purpose of 8.2.M.4.?

GREYMULE

I am not disputing your call for a rewrite or an exeption to the rule.
I am not saying that the question, as written,should have another answer.

I am saying that the play as described can be resolved within the existing rules without letting a run score.

The rule by the way on interference after being declared out reads
A runner continuing to run and drawing a throw may be considered a form of interference,

In this case the batter is out when the umpire declares infield fly, and his continued running on the play you described would easily fit that interpretation.
