IMHO,I believe that it should have been stated, "IF ALL the spokes are wired in the same + to - respectively, THEN the split ring takes care of? NOT needing an AR".
If you look at the drawing I put in photos, you will see the different polarities on my spokes.
They are also spread between A and B portions of the TT.
If you look at some documents out there, like the wiring in FIG 6, you will see how the polarities matter.
I would love to hear what Alan thinks.
