Every enemy with thornmail deals damage to him based on the damage they would get pre mitigation. For example, if 3 enemies have thornmail and are hit in order of 1st, 2nd and 5th, the first deals 30% of twitchs ad (assuming no crits) in damage to him, the second would deal 30% of 80% (because of the damage reduction), which is 24%, and the fifth would ge 40.96% of his ad in damage, so thornmail will deal 30% of that, which is 12.288% of his ad in damage.
