As I see it, all suggested edits should have been rejected.
There is absolutely zero reason to bump these questions/answers to the front page years after their initial conception because of the minute distinction between "disjoint" and "pairwise disjoint" -- more so because it is often glaringly obvious from the context which one is meant.
This especially holds for the (fortunately rejected) instance where you changed a quote from a book, where the subtle distinction may well have contributed to the confusion.
Please, continue your editing effort, but focus on questions in need of improvement. These are posted by the hundreds every day, so there's more than enough work to do.
