In that example the "detection" of the signal requires recovering the
original waveform.

You think any convolution of a square wave form with its kernel could
look like _that_?

You think an authoritative article is necessary for an _example_?

Maybe you think the author put that nonsense in because he wanted to
help out anyone trying to mislead on how match filtering can be used
for wave form recovery?
