This is the correct interpretation. Armor is only broken in one "strike zone" even if it is technically all one piece (such as your maille hauberk).
"5.1.4 - The front, back, and sides of any part of the body are considered a single strike zone for armor coverage. Hits anywhere on armor on the left leg are considered hits to the "left leg armor," and hits to a fighter's armored chest, sides, and back are considered hits to the "torso armor" even if the hits land on different pieces of armor such as a breastplate and backplate. Think of armor protection in Dagorhir this way: armor lessens the damage from some types of hits, but does not eliminate damage entirely. Hence, an armored fighter will "survive" the first blue weapon hit to his back, but a second blue hit to the same fighter's chest armor will have done enough damage to "kill" the fighter."
Also, a single green to an armored torso will never kill the player, even if the armor is broken.
"5.1.10 - A one-handed green thrust has no effect on armor, even if previously struck with a blue weapon."
EDIT: I should also note that even though your hauberk might reach down to your knees, it's a little bit of a stretch to call it leg armor as well as torso and arm armor. You could argue it, but I definitely wouldn't.
