Did Anderson Break The Rules?

Adam Rubin at Surfing The Mets writes about the Marlon Anderson and if his slide broke the rules:

Anderson's point is that how is this different from what happens all the time?

Here's the rule:

A batter is out when a preceding runner shall, in the umpire’s judgment, intentionally interfere with a fielder who is attempting to catch a thrown ball or to throw a ball in an attempt to complete any play:

Rule 6.05(m) Comment: The objective of this rule is to penalize the offensive team for deliberate, unwarranted, unsportsmanlike action by the runner in leaving the baseline for the obvious purpose of crashing the pivot man on a double play, rather than trying to reach the base. Obviously this is an umpire’s judgment play.
