The zero tolerance approach to punctuation

From the New York Times online, in an article discussing the varying fortunes of the semicolon:

Correction: February 19, 2008
An article in some editions on Monday about a New York City Transit employee’s deft use of the semicolon in a public service placard was less deft in its punctuation of the title of a book by Lynne Truss, who called the placard a “lovely example” of proper punctuation. The title of the book is “Eats, Shoots & Leaves” — not “Eats Shoots & Leaves.” (The subtitle of Ms. Truss’s book is “The Zero Tolerance Approach to Punctuation.”)

Am I the only one who sees the irony here?
