"Post Transform":
   Change = (Changed data set - Original data set)

Or in poser language:
    Morph = (Sculpted figure - Original figure)

Or also:
   delta_array == modified_vertex_array - original_vertex_array.

Each morph is a "post transformation" - or have I misunderstood something again?

Shrug. In Poser parlance apparently Transform is a translation, rotation, or scale. As in when you save a pose the option to save Body transformations. I seem to recall someone mentioning that it also pertains to the position of morph calculation as written into the file, as in how JCMs are written, don't hold me on that one though. I don't see why your interpretation would be wrong, makes sense in an encompassing kinda way.
