Adloquium gives a damage shield based on the amount of health healed, right?

I'm just gonna copy/paste from another thread and change the wording and numbers around:

Adloquium heals for 100.
PLD has 20% damage reduction, gains 100 damage shield from adloquium.
WAR has 15% healing potency, gains 115 damage shield from adloquium.
Enemy does 115 damage.
Enemy breaks through the WAR's stoneskin in 1 hit(115 damage taken)
Enemy does NOT break through the PLD's adloquium in 1 hit(92 damage taken, 8 shields remaining)
