As it happens, a similar sequence with many more footnotes is
described in the December 2008 issue of the BW, and this puts some
context into the discussion:

Author Cohen explains the footnotes thus:
a = artificial; game force
b = five-five (but not 3=5=5=0)
c = sets spades as trumps
d = control-bid
e = Last Train (artificial general slam try)
f = key-card ask for spades
g = 0 or 3
h = wholesale king ask [per Cohen: South assumed 3 key cards
opposite and was trying for a grand slam]
The slam went down on a club lead and a heart shift but West spend 2-3
minutes deciding what to play at trick 2 after East played the queen
of clubs on the ace of clubs lead.

What was the redouble? Absent specific understanding, I would have
assumed first-round control.

Redouble was not explained n the BW as I recall, but I can always
double check later.

2D is pretty unusual with a maximum. I am more inclined to treat the
given hands in this fashion
1H - 1S
3D - 4S
All pass
4S = with singletons in hearts and diamonds, partner's strongly bid
suits, the slam does not rate to be good.
Alternatively...
1H - 2S!
3D - 3S!
3N!- 4D!
4H!- 4N!
5D!- 5S
All pass
2S! = strong jump shift, a bit out of the ordinary, one would rather
expect S AJTxxxxx H A D A C xxx or S AKxxxxxx H - D A C xxxx something
like this, since opener is limited in hcp's
3S! = slam try, establishes spades
3N! = slam try acceptance
4D!,4H! = first or second round controls ( 4H! = still interested in
slam since no club waste )
4N! = RKCB for spades
5D! = 0-3 keycrds
B.R.
As I thought, no comment on the redouble was made, either in the text
or in the footnotes.
