Confusion on pspectrum time/frequency resolution

I'm confused by the outputs of the pspectrum([],[],...,'spectrogram','Frequency(OR Time)Resolution',[]) outputs, as I am getting approximately 4x as many samples as I should in the frequency domain (e.g. a frequency resolution of 0.001 is returning a CyclicFreqs vector with 4001 elements), and I'm getting twice as many Time elements as I specify with 'TimeResolution'. I've read the documentation on pspectrum, but is does not give me any indication as to why MatLab is giving me a higher-fidelity output than I'm asking for.
