Headshots have their own dmg and crit multiplier so they still deal some dmg even tho your crit multiplier is below 0,0.

Also you may proc (what i'd hope) some elemental dmg what should be pretty great with this Riven. Additionally your elemental proc might favour against the targets you tried it. I am also not quite sure if a mod really should deny your crit multiplier below 0,0 and it might be just like 0x crit multiplier for the game. I remember some strange stats with 4xCorrosive Projection when you could lower the Armor below 0%...

Sorry that I wasn't much of a help because I can just assume these things, but I think it's most likely the separate dmg multiplier from enemy mobs on their head.
