Yeah, it doesn't. I think teh only reason to normalise the vectors is for ease of calculations with them?
You shouldn't need to use updatenormals() unless you've altered the vertices of a mesh, or you have built a mesh in a modeller and done some alterations to the normals.
btw, sswift wrote a much better updatenormals function in the code archives :o)
