The plausible explanation for "center-embedded clauses"(CAC) is this: whenever there is an issue of ambiguity about a concept in the main clause, CAC will clarify that ambiguity. If one makes CAC as an independent clause, this independent clause can clarify, or reduce ambiguity, in all clauses of that paragraph or the whole contract (all paragraphs). In some unforeseen circumstances, making CACs as independent clauses may cause problems. I see CACs as footnotes, directly attached to the clause.
