The type of damage dealt by an attack seems to have a lot of modifiers applied. It seems like only physical on-hit damage is considered "part of the basic attack", whereas true and magic damage are just applied at the same time. You can see this effect in terms of lifesteal. You can't lifesteal off magic damage, even if it's an on-hit. Thornmail seems to reflect all the same damage that lifesteal considers for its healing.
