Depends on what you call 'over-compressing'. If you're 
using heavy compression to squeeze out the last dB on
material that is already high level most of the time
you're right. 

OTOH, compressing a classical piece from 40dB dynamic
range to just a few dB is certainly 'over-compressing'
to my taste, yet it would probably make little or no
differerence to the value measured by 'normalize -n'.
