Wiring design for USB voltage and current tester
Your diagram seems correct to me.  It's not the same as in the instructable.  I think that your diagram makes more sense.

The instructable shows that the data wires (red and green) are cut.  That means that the USB slave device under test will not be able to communicate with the host.  The slave will not behave naturally, if it can't communicate.  Also by the USB specification, the slave will not be able to receive more than 100mA supply current.  If it the data wires are intact, the slave device will be able to behave naturally.

One more thing.  Connect-through the EMI shield around the cable.
