It's just a short-circuited transmission line. You feed it pulses and the reflection coming back from the short-circuit is equal, opposite and delayed with respect to the input pulse. So you see at the input a pulse which is as long as the line delay, not the original pulse length.

One cannot tell from a picture. You had best ask the maker, or search out Alan Blumlein's patent (from the hundreds he was granted).

google "nonlinear transmission line" and "shock line", and maybe look up McEwan's patents, stuff like

I agree. It's a poor explanation.
This is much better:
