For the scopes that over-range in cold weather, that makes sense because, the contraction of the scope body will pull the objective lens further in, which has the effect of re-parallaxing the scope to a distance closer to infinity (as I have to wind out the adjustable objective on my Hawke scope to bring the focus closer).
