I do not understand why one has to tie this knot in the first place !
...
The standing end is going to ignite the "exploding" segment before the pull of the trigger !
The knot is stable until released, unlike the popularized
highwayman's hitch --noting that there is that issue
of when the nip is sufficient upon the slip-tuck/toggle
(one might prefer to locate the nipping opposite the
load point for quicker/surer tension reaching this point;
alternatively, there are ways to toggle the ultimate
slip-tuck to prevent the drawing out of its legs).
When to use this?
If one were single-handedly (i.e., sans ground crew)
lowering some several items to the ground,
the line could be freed from the object and
returned upwards for continued lowering
(w/o say having to pull through an entire
length-of-lowering part of line that slipped
a hitch that wasn't a "slip-free" hitch).
(An alternative method could use a stout line
for the lowering, load bearing, and a thin line
to a toggle for release.)
