While it's not possible to duplicate an existing key, it is possible to create duplicate keys in the first place - you can't get the secrets out, but you can write identical secrets to two or more keys if you want to. This adds some convenience, though it also does add some risks e.g. in case of breach you can't tell which token was misused, you can't invalidate a lost key without invalidating others at the same time.
