I've not heard the term "hi coefficient" used in filter dsp before.

As a reverb is a network of delays with feedback I don't
disagree with your analysis of course.
Except that the sound isn't reverb-like.

There's clearly a repetition every 180mS here


from 2:48

but then there's longer cycles audible too.

...but there's no glissandi within the freeze
...however, unlike a reverbed glissando there's
  still clearly defined constant frequencies

need to hear it without Youtube sound compression,
but I'm still puzzled
