Even if the edits did not put the question on topic, were they invalid edits?
There is no "rewording" of home networking that can ever make it on topic. You admit with the original post that it was "home wiring". That is absolutely beyond scope here. In short, what has been said cannot be un-said; your edit didn't rework anything, but removed a relevant part of the question that, unfortunately, makes it off topic.
Why were they rolled back (twice)?
Edits that obscure that fact will be rolled back to avoid confusion, and restore the original intent of the question.
Why did a moderator ask me to reword the question to be on topic, then rollback the edits that were asked for?
The comment attached is the same comment attached to all "on hold" questions. Moving questions directly to closed was seen as too harsh, so everything goes through a "hold" period first.
