I wonder how the terms of that work exactly in practice. For example I'm pretty sure Humble Bundle includes games that are on Steam every now and then, with a pretty solid discount if you consider what you get for your money.

In practice it means Steam reviews the key requests you make for third party bundles and sales. If they decide the deal is too generous, they may deny the key requests until you've offered the game for a comparable price on Steam.
