The new-domain proof is a direct-sum proof. The old-overlap proof applies to the entire new sum. Thus no untested intersection with an already glued sum remains.
All tensor products and separating projections used in these arguments are algebraic. None identifies a presentation map with a quotient map or a topological isomorphism.
The following implications are not asserted:
