It seems the author is using the word logic, so logic boolean algebra suggests the classical case. Perhaps what is not trivial is that one can use that rule to deduce the other axioms. So that is not the theorem what is…
Perhaps using Grobner basis for formal proofs [1],[2] could be similar to what appears here, that is during the proof the length of the terms (or polynomials) can grow and then at the end there is a simplification and…
