Is soul vortex saving me from disease?

[Immaculate]

I have a unit, a tough little piece of cavalry which continually uses soul vortex in battle but has also picked up the diseased affliction. The thing is, as long as he is involved in combat, his hit points sort of vary up and down and he doesn't die.

Am i imagining things or is he keeping the sucked out life from combat and preventing the disease from killing him thereby?

I.

Disease prevents a unit from healing to full hitpoints at the end of every turn, causes one hitpoint of damage at the end of every turn, and tends to cause other afflictions either through the damage or through some other mechanism. Units that regenerate will not die from disease as they will still heal at the end of every turn, though they will still gain afflictions. Undead and demons are completely unaffected by disease. Any unit that is healed during battle, either through regeneration, the healing spells, or life drain effects (soul vortex, wraith sword, hell sword, blood thorn, etc.) will not die from disease as its hitpoints can be replenished during battle.

At least until it becomes mute/feebleminded and can't cast soul vortex anymore.
