When you power up a RaspberryPi with its own power supply, and then connect this hub, you are able to remove the raspberrypi power supply and have it remain on with the voltage that feeds back down to the Pi.
This is against the USB spec and dangerous, this can potentially damage the Pi and any other USB equipment including laptops or PCs.
Though, without the power connected to the hub at all, it works just fine as an non-powered usb hub
