IP vs catchers obstruction

[IRISHMAFIA]

Start by noting that in the OP from the other site, it did not state the pitcher was intentional in rolling the ball, but I could understand how it could be read that way.

However, to Steve's point, it also read that the catcher jumped up and ran out to get the ball. It doesn't even state if the catcher attempted to get the runner out.

My response is based on this not being an IP and the ball was still rolling toward the plate and as long as that is the case, I'm assuming the ball was hitable.

ASA 8.1.D.3 states that if the catcher does this, the ball is dead, batter is awarded 1B and only runners forced advance.

Well, why is this different than other CO where the manager gets the option? Maybe the manager would prefer the batter stay at the plate with a runner on 3B.
