Huh? "And don’t worry about a single drive or peripheral tying up the Thunderbolt port: You can daisy-chain as many as six devices, including your display."
"You also have more than enough bandwidth to daisy-chain multiple high-speed devices, without using a hub or switch. For example, you can connect several high-performance external disks, a video capture device, and even a Mini DisplayPort display to a single Thunderbolt chain while maintaining maximum throughput."
I think you misread it.
