in both cases the written pitches ARE transposed (sound) down an octave, as explicitly indicated by the 8_clef in the version, and the 8vb indication in the second. indeed, the whole raison d'etre of those indications is to show that the displayed pitch is transposed an octave lower.
in the case of a 'transposing at the octave' instrument such as piccolo or double bass, the clef change or 8va/b sign is implied and simply omitted as a convenience.
agreed the sounding pitch in each case is the same, but this is a notational, not a sounding issue.

Even more to the (semantic?) point, the following two are IDENTICAL with respect to pitch:
\version "2.11.37"
\include "english.ly"
musicClef = \relative
{
\clef "treble" f e d c
\clef "treble_8" bf a g f
}
musicOct = \relative
{
f e d c
#(set-octavation -1) bf a g f
}
\score
{
<<
\musicClef
\musicOct
>>
}
In NEITHER case are the PITCHES "transposed" in any way -- in both cases, the PITCHES are identical... and the same as "the original".
What's happening here is that, in Version #1 (the clef change) we're explicitly showing that the notation is in a different clef, whereas in Version #2 (octavation) we're using a shorthand to transpose the CLEF ITSELF (while leaving the pitches exactly where they are)!
Therefore, I suggest something like "Clef transposition and octavation", or something like that, so that it's clear that the PITCHES are not being transposed in any way.
Cheers,
Kieren.
