I think that Winslow and I are referencing of two different types of Transposition. From Wikipedia (http://en.wikipedia.org/wiki/Transpose_music):

"Chromatic and scalar (diatonic) transposition:

There are two different kinds of transposition, depending on whether one is measuring intervals according to the chromatic scale or some other scale. In chromatic transposition one shifts every pitch in a collection of notes by a fixed number of semitones. For instance, if one transposes the pitches C4-E4-G4 upwards by four semitones, one obtains the pitches E4-Gâ4-B4. In scalar transposition one shifts every pitch in a collection by a fixed number of scale steps relative to some scale. For example, if one transposes the pitches C4-E4-G4 up by two steps relative to the familiar C major scale, one obtains the pitches E4-G4-B4. If one transposes the same pitches up by two steps relative to the F major scale, one obtains instead E4-G4-Bâ4. Scalar transposition is sometimes called diatonic transposition, but this term can be misleading, as it suggests transposition with respect to a diatonic scale. However, scalar transposition can occur with respect to any type of scale, not
  just the diatonic."

I was referencing of Chromatic transposition so the music would sound the same at another pitch, but Winslow seems to be referencing of Scalar (diatonic) transposition which would change the sound of the music.
