I can't say this for certain, but it's possible both the hub and the ports on the computer don't have isolated 5V supplies, so the 5V being supplied to the hub is actually feeding back into the port, and from that port going to all the others that are powered together on the motherboard.

Not exactly dangerous, if my above postulation is true, but definitely not great design practice.
