It is not clear when the projects merged, but this was a common theme in Apple at the time. Middle-managers were involved in an intense for much of the late 1980s and early 1990s, gathering projects together into "über-projects" that contained enough important code to make them "unkillable". Sadly this often delayed the projects dramatically; one component running behind schedule forced the entire collection to be delayed so they could be released "complete". QuickDraw GX was one such victim, and delays and changes of direction in TrueType and other problems greatly delayed the introduction of GX.
