Don't follow that one. In the L network, the Q is fixed by the impedance
transformation. In the pi or the T (one of which is the dual of the other),
having the three variables allows Q to be a chosen parameter.

Although I suspect we may have to define what we mean by the circuit Q here -
the usual trick in a pi is that it's  Rin/Xc1.
