Except being treated as functionally the same for mechanical purposes does not equal being the same - if that was the case, there would be no actual difference between a Gift and a Discipline because they've both been used to represent the same things. DKoJ maintains a binary soul as opposed to the unitary soul of core Wraith of the same era, which is an important distinction that you're trying to gloss over. The PG, released the same year, has a similar distinction - Hun and P'o remain distinct from, if analogous, to the Psyche/Shadow. The divide was increasingly bridged over as things went, but it was there and distinct at the start.
