Oversight in editing? Or intentional?

I say the current definition is just an oversight from when they changed the rule for 2009, but one that I wanted to point out.

And I'm saying it is irrelevant since they were never "approved" to become "non-approved".

Parse the sentence like this.

The official bat shall be [smooth and round to 0.050 inches in diameter] and [bear either the ASA 2000 certification mark or the ASA 2004 certification mark as shown below ( in the 2010 ASA Rule Book) and must not be listed on the ASA Non Approved Bat List.]

IOW, the "must not be listed on the ASA Non Approved Bat List" applies only to those with an ASA certification mark on them which excludes all the bats to which you are referring.
