How can it possibly be telling you there is a limit on what can be moved which prevents you taking hull damage?
Redirect says : " The defender chooses one of its hull zones adjacent to the defending hull zone, when the defender suffers damage from this attack, it MAY suffer any amount of damage on the chosen zones shields (up to the shields remaining on that zone) before it MUST suffer the remaining damage on the defending hull zone.
People rarely redirect more damage than they have shields on the adjacent hull zone, but that is a limitation we have applied, it is not applied by the wording of the rules text, say you take 5 damage, you can redirect 5 damage, it does not limit anywhere the amount that can be redirected, only X17s limit how much can be redirected.
Also the wording is telling you shields are removed first, before damage is applied the the hull, not shields must be there for redirect to work.

ovinomanc3r highlighted the key part you're missing, TheEasternKing. The damage remaining must be dealt to the defending hull zone, which is not the hull zone being redirected to. The RRG is very clear that there is a limit to what can be redirected (the amount of shields remaining on the chosen zone), and any excess must be dealt to the defending hull zone. Since the hull zone being redirected to isn't the defending hull zone, then you cannot apply damage directly to the hull of the hull zone chosen by the redirect ability.
To follow with your example, say your full health ISD is being attacked on the front hull zone. Your front hull zone is the defending hull zone. You choose to use your redirect, and you choose your right side. Damage is calculated, and it comes out to be 5 damage. You assign damage points one at a time. Since there are 3 shields on your right side, you can redirect a point of damage there three times ("up to the shields remaining on that zone"). When you go to assign the 4th point of damage, there are no shields left on the right side and you have already met the "up to the shields remaining on that zone" criteria. The remaining two points "must" be suffered to the defending hull zone, which is the front hull zone.
