If you sample a signal at too low a sampling rate, you won't necessarily get alternating samples. You could end up sampling only near the toptops (for awhile), or only bottoms, or only zero crossings, etc., which would look like samples of a "smooth" waveform of a much lower frequency than at some fixed value such as half the sampling frequency.
