freqz question (clarified)

Just to clarify my previous question, Matlab's output of freqz is as follows:
freqz(b,a,...) plots the magnitude and unwrapped phase of the frequency response of the filter. The plot is displayed in the current figure window.
Why does Octave's freqz not plot magnitude and phase?  Instead it plots 1) pass band, 2) stop band, and 3) phase.  Plotting a separate pass band and stop band doesn't make sense to me.
