It's NOT (since 1980)! That's the point of this discussion.

Lock and unlock are opposites. Only in some strange parallel universe
are over-write and insert opposites. Insert vs. over-write mode are
also not even opposites. Delete and Insert are opposites. Over-write
feels like a programming error when it happens to me!
