Actually, it does. It shifts ∗frequencies∗, not ∗pitches∗. The difference of
course being that pitches have an exponential relationship to frequencies.
So as the shift increases, the partials of the output signal are pushed
further and further out of line with the input signal's. That's a quick,
crappy explanation.
In a nutshell, if you understand how a ring modulator works, a frequency
shifter does the same thing but instead of producing an upper and lower
sideband, it can produce one, the other, or both (at least a full featured
one has a switch like this on it).

meanwhile - a serious question to anyone in the know:
what exactly does mr bode's frequency shifter do...? (and don't say it
shifts frequencies)
