If he sent 1 transaction for each of his 0.00000001 LTC output, he would have needed to pay 0.1 LTC for EACH transaction. Or at least 0.02 LTC per transaction with the relay transaction workaround. I don't see how that's way worse. He's taking advantage of the fact that the fee system charges less fee for dust spams using sendmany. Please see my previous post on how I want to fix that.
