Because you're using it wrong. First, fresnel reflection varies from 0 
to 1 by default, so "reflection {fresnel}" isn't even remotely 
equivalent to "reflection {0.2, 0.4}". And second...glass reflection 
isn't really very variable. Get a piece of glass and look at it from 
various angles...the reflection stays pretty much the same (there is a 
sharp increase where total internal reflection starts, but that is a 
separate effect that POV also simulates). Water and many ceramic glazes 
and plastics do have highly variable reflection.
