I also thought it was applying it to the normal statement only, but it 
is applying it to the image pattern statement also.  In my example I 
used two normals statments one for below 0.5 and one for above 0.5.  
When uv mapping is applied you can clearly see that the image pattern is 
being uv mapped.  It is probly applying it to the normals to though 
causing the scaling.  Either way I don't see where it says it will apply 
it to both.
