Actually I think, engineers prefer to use frequency sweeps instead of pulses nowadays

How fast of a sweep are you talking about? Seconds or milliseconds? Is this the 50 and 80 ms bit that the paper mentions?

If we use a rising frequency sweep, the harmonics will be gener- ated ahead of the same frequencies appearing in the signal. So after deconvolution, any dis- tortion will appear as spurious peaks in negative time in the impulse response, and most of it can then be edited out easily.

What a great way to use an artifact of the FFT to one's advantage. Awesome!
