I don't think it means you'll get more power, but the power supply will have more reserve capacity so that when peak demands are made, the reserves will be there. I have a six channel receiver that I use in 5.1 and my sales rep (in whom I have confidence) explained it to me this way. I'm no engineer, but it sounded reasonable. Remember that power output measurements that are below rated specs are usually simultaneously driven channels and it is a rare moment when all your channels are outputting power simultaneously in the real world. Of course, all other things being equal, more power on hand is better. But ergonomics, reliability, features and even looks play a role as well.
Good luck with the receiver hunt.
