The first quote might have been an omission since 3d 'creatures' have a mind/body/spirit complex, but here is how I see the wanderer complex in 3d.
A wanderer ultimately retains the spiritual experience they have gained, but portions suited to the 3d mind/body limitations essentially filter (reduce) the potential of the spiritual aspect. In other words you have limited access (3d potentiator) to the (4d or higher) matrix of the spirit as mitigated by the veil. Theoretically you would regain your full complex once in a 4d environment, or sent back to your SMC.
Basically you can't have gods walking around all Willy Nilly down here lol.
