Hmm, what’s your source for that? They have a total net-wealth of something like $160 billion, so it can’t be more than a factor of 3. And it seems quite likely to me that both of them have at least some values that are not easily captured by “save as many lives as possible” such that I don’t expect all of that $160 billion to go towards that goal (e.g. I expect a significant fraction of that money to go things like education, scientific achievement and other things that don’t have the direct aim of saving lives but are pursuing other more nebulous goals).
Gates and Buffett have pledged a lot more than that.
