Do I need to re-run guided setup, when moving to new zipcode, but not changing cable provider?

I will be moving to a new house (a 1 mile move).
I will have the same cable provider.
However, my zip code will change.

According to the official Tivo support:

one has to re-run guided setup when changing zip codes.
But is this really necessary, if the cable provided (and channel lineup) will stay the same?
The zipcode listed in the "System Information" will be incorrect, but does that...
