I have not read Joes page in a while or his page on this glue if there is one.
I dont see why the veneers cant be taped with quality veneer tape and then ironed down as described.
White glue is considered weakest glue for holding up to moisture and plenty of peopl apply water based dye after using white glue.
Sorry I dont have a real answer for you. more investigation with the people who are making the claims might be in order. The claims dont make a lot of sense to me
