Oh, so to be clear, the phase angle of the impedance refers to the relationship of the voltage to current.
The phase angle of the output refers to timing.
The only thing they share is that impedance and output are complex numbers. That is, they have a magnitude and phase. None of those four numbers are equivalent.
