Actually there is no error in the wiring, this is traditional LP wiring..previous reviewer is correct in that when the switch is in the middle either volume pot will impact the volume on both pickups, turning any volume pot to zero will short the output to the ground...You can switch the pot terminal connections as suggested in that review of course. But then this re-wiring has problems too! In the original diagram each pickup has a constant load (the resistance of the volume pot), if you switch the wiring the load on the pickup will be different at different volume settings, hence the dynamics of the circuit will change...Without getting into too much detail, pick up is basically an LRC circuit, and external connection will affect its electrical response etc...you might wanna try both and see (or hear)....
There is actually a small error in the diagram - the wire from the pickup should go to the middle terminal (wiper). The way the diagram is currently, turning down the volume on either pickup will impact the volume on both pickups, if the switch is in the center position. Essentially, turning down the volume shorts everything at the switch to ground (in the middle switch position).
