Strategos Islin has the following passive:

"Whenever this Champion is attacked, heals themselves by 1% for each 500 DEF this Champion has. Heals all other allies under [Ally Protection] buffs placed by this Champion by 30% of this skill's initial heal."

Does that mean if you use the Defense Masteries such as Selfless Defender (second bottom on left) or Bulwark (bottom row), where he recieves damage for other allies, does this trigger his passive?
