Consider the primary circuit (with however many coils it has - two in 
this case) in isolation. It resonates at 150kHz odd. You couple a 
resonator to one of the coils. It also is tuned to 150kHz. Whichever 
primary coil is not coupled is simply "off-axis" inductance. Couple 
another 150kHz resonator to the uncoupled primary coil. Nothing about 
the primary has changed (except that it is now coupled to two 
circuits absorbing energy at its resonant frequency. Is there still a 
mystery?
