The primary is as in a two-coils system. The secondary and tertiary 
inductances add and resonate with
the topload+L3 capacitances. Both resonances shall be at the same frequency:
1/(2*PI*sqrt(L1*C1))=1/(2*PI*sqrt((L2+L3)*C3)))
The capacitance across L2, C2, messes up the tuning if it is significant.
You can accept the loss, or can eliminate it with a particular design 
method.
