I think a point that has been undermentioned is this: all the games in these bundles are at the end of their life cycle. Aquaria, World of Goo, etc have all been around for years. Everyone who cares enough to know what they are and shell out cash has already done so. Aquaria already had plenty of sales, World of Goo already had a Pay What You Think is Fair sale. Their usual mini-markets have been tapped out.
So, along comes Humble Bundle. With absolutely nothing left to lose, each penny they bring in after that is a miracle penny from heaven, and every piece of publicity they bring in is someone they didn't reach before. New Players get to try the games "they'd been meaning to get around to" or had never heard of, now at a price they pick so will find fair. It's kind of like roasting up some BBQ beast, eating off all the meat you can carve, and then burying the scraps- only to find that you can get extra mushrooms to grow and eat even more off your feast.
Would you take a new game and bury it directly hoping to get mushrooms? That's doubtful. You'd want to tap your primary market first. Is the mushrooms phase likely to detract from the BBQ phase? Not too likely. People with a hankering for fresh BBQ game content probably don't want to wait around through the life cycle of the game to eat the older mushrooms. Everyone hungry to pay for delicious bacon still will- those willing to settle for mushrooms didn't really crave the BBQ experience enough to pay for it anyway.
