I realize that the turns count he did has some plus-minus error, but any parallel windings must have the same number of turns, or else you get a "shorted turn" effect.Which basically would look like ((resistance of both windings) loading the (difference of the number of turns)) load circuit. Oh, maybe one could exploit this effect to dampen resonance?
