If you apply the shorten-pair property before the "d1" note, in your 
example
above, you should get the behaviour you want.   Applying the property 
before
the "c1" affects the length of the first bracket, because the property is
applied before the first bracket is created (with the first 
\sostenutoDown).
Applying it before the "e1" doesn't make any difference to the second 
bracket,
as the bracket has already been created (with the second \sostenutoDown)
before the property is applied.

It's the default to not include the final note, as (IMO) this represents
releasing the pedal and depressing the note simultaneously.
