It doesn't have to be strictly damage affecting elo changes in that case. Say you're matched up with a pretty bad teammate but you manage to deal lots of damage before eventually losing the 2v2. You lost, so clearly you should lose elo, but you also played well, so maybe gain some too. Overall, it could be that you'd want to balance good performance elo gain and loss elo loss for a net ~0 elo gain.
If it just so happens that you win, then you both won and did lots of damage, so you should get double the elo, while your teammate which is kind of bad shouldnt get as much just for getting carried if they did less damage.
