Seems that nobody reads anything nowadays.

It is clearly stated that the debuff is a hp FREEZE and not in anyway a healing/regeneration reduction. It will freeze the target's max health at its current health:

EX: Shen has 1400/3200 health left. The debuff is applied to shen, now he has 1400/1400 health left for the duration. Any heals/regeneration effect cast on shen will go on standy and be actived once the debuff ends. Lets say soraka cast a 400 heal on shen while he is debuffed for 3 seconds. If shen isn't killed within the 3 seconds hes debuffed he will receive the heal. Now if they bring shen, for example, down to 200/1400 HP and the debuff ends, his health will return to normal and he will be healed for 400 thus getting 600/3200 Hp.
