It's an effort vs benefit calculation. Can you say how much of that savings will translate to dollars in your pocket? In most large companies, we can't. And when you're in a company making tens of billions, a saving of $200K is rounding error.
Then there's the psychology of it: If enough other people work extra long hours to get those savings, they're not getting a larger bonus than me who isn't. When you scale this kind of reward incentive, what you'll get is most employees not bothering - they'll get the bonus anyway.
