Yea, it's a difference of altering base stats vs total dice rolled. Range 3 and other defense bonuses affect your defence dice count; they don't alter your agility.

Your total defense dice is your Agility (minimum 0) plus any bonuses, such as obstruction, range 3, pilot/upgrade abiliities, and so on. If an ability were to reference your total agility, such as Proton Rockets, these wouldn't affect it (even though you can't fire prockets while defending, just an example). But Stealth Device or R2-F2 would affect your actual agility value, and thus also boost prockets.

This is similar to how most bonuses to your total attack dice rolled don't change your Primary Weapon value, e.g. for the purposes of Guidance Chips. For example, Alliance Overhaul or Jan Ors affecting an ARC won't make its guidance chips mod to a crit. However, Expose would increase your primary weapon and improve guidance chips, and also lower your agility (including for prockets).
