It is quite question. I guess only original designer knows right answer.
My presumption would be that second reciver - direct receiver with ferrite rod, actually have unusuall role here. If those coils are fully resonant, than weak signals would not be enough to disturb balance. Therefore some extra "disturbing factor" must be added in overall circuitry - i guess direct receiver is there cose of that..But than again, if i am right, why using fully resonant coils???

There is two coils on two ferrites cores in the same axis separated by a "crititically adjusted" gap.I am not sure if both coils are wound on the same core or not.
