Cases of this kind of error in the doc are always interesting to me, because I wonder when the error entered (and desperately hope it wasn't my fault). This one, in fact, dates to the Cookbook. See p. 541 of the version that shipped with VW 2.5.
There's an AR, and it will be corrected. More than corrected, maybe say something enlightening.
