However, the pulses actually going down that cable are at a much faster rate, going at least 40 times faster. (stereo and 20 bits). So the individual pulses are measured in a few hundred meters. If you are worrying about the SPDIF cable, why are you worrying about word clock pulses, pulses that are generated at the opposite end of the DAC from where the cable enters?
If you are looking for an explanation as to why changing the cable length a few inches matters, well that's because the DAC gets a different signal, albeit one with the same bits. Then, given slightly different input it produces slightly different output. (This isn't logically or mathematically necessary, rather it happens due to the way the DAC is built.)
