It's intentional.

They would've not DRM chipped a freaking cable if not for them selling them for $20.
Take a look on my experience from a decade ago:

- jacquesm 5y agoI would like to see a picture of that circuit, not just a diagram. I've used this trick to good effect, and also used another trick: to use the circuit board as a balancing resistor. Just make the track a little bit longer for instance by routing the wires less than efficiently or by putting a little wavy line in it and you have a very low resistance resistor just perfect for balancing out the differences in diode switch speed and bias voltage. In electronics not everything is what it seems to be at first glance. For an encore check out pcb fuses, coils and even capacitors.
