Both may be true accounts of what wierwille actually said. I don’t think it’s a matter of conflation on wierwille’s part – where he had combined the two ideas. Maybe in a deluded mind that’s usually inclined towards plagiarism the source of the idea for The Way Tree simply “evolved” ...
...and the more I think about it, the imagery of the way tree may very well be the moot point in all this...as far as the structure - how the whole organization was arranged to supposedly function "properly", it does seem to emulate the AA somewhat - although I think TWI's HQ is far more overreaching in authority and control (when compared to the 12 steps of AA ) ....and as far as describing the function of TWI, it's more along the lines of multi-level marketing " ...where the revenue of the MLM company is derived from a non-salaried workforce selling the company's products/services."
