it works fine. Just don't power on the 360 before you see the windows loading screen.
He's not using the 360 to power the drive.
Might be worth waiting until Windows has booted completely before plugging power into the connectivity kit. This works for me, albeit using a USB-SATA adapter from eBay (search eBay for ISLB). I couldn't get my onboard 6421 to work with Hitachi.
