Thornmail and Sunfire aren't spell damage; they don't apply spell effects (Rylai's, Liandry,) Spell Vamp is also a spell effect, just as Lifesteal is an on-hit effect.

I've yet to test it in game, but judging by the wording, it should now heal the user for dealing non-physical on-hit, or even DoTs.
