Why 8-8-Y?

[Dakota]

According to the Western PA web page ( Western Area of the Amateur Softball Association Of Pennsylvania ), ASA has approved a new rule 8-8-Y, which if I use the text on the W-PA web page, will read something like the following:

THE RUNNER IS OUT. When after a conference, base runners switch positions on the bases they occupied. Each runner on the improper base shall be declared out. In addition, the head coach shall be ejected for unsportsmanlike behavior.

The rule itself is pretty straightforward. I'm interested, as Paul Harvey says, in the rrrrrrrrest of the story.

This strikes me as an odd rule. The kind that will make it into the rule book only as a reaction to some specific situation or situations. Does anyone know the story?
