This is a legacy of the RC data format. The signal is transmitted as a series of short fixed width pulses, one pulse per channel. The time between each pulse gives the output pulse width for that channel. This repeats for the rest of the channels. 20ms gives enough time for 8 channels plus a sync pulse. This format is very easy to decode with a simple counter.
