According to the Descent rulebook page 15:

"A knocked out hero may still recover damage from other heroes through the use of skills, potions, and being revived (see “Revive a Hero” on page 10). If a knocked out hero recovers at least one damage, he immediately replaces his hero token with his figure and may perform actions as normal on his next turn."

A hero being "revived" by another hero seems separate from simply being healed. I would argue Rendiel only triggers his Hero Ability after performing a Revive action, or his feat (which mentions the word "revive".
