I fail to generate a time-domain waveform whose amplitude comes to zero quickly after merging. But, I made waveform the same to Hunter's way and the whitened waveforms do look similar.

In Hunter's test data, the amplitude also doesn't come to zero after merging(as you can see in Fig. 1), and there is a vibration, although it is not obvious. I think whitening step reduces it.
