They meant that you’d get the same message no matter what unrecognized option you use. So it’s not like they added a specific check that if you type in -h they will give you the message, but instead you get the same message for any unrecognized option.
The thing in the OP only occurs if you type exit, so they specifically added that message to be shown when the interpreter clearly knows what you want, but you just didn’t say it exactly right.
Not always, way too often you just get a variation of “invalid option, use --help to get a list of options”

I mean, if I didn’t use a correct flag, my next command will probably include -h / --help
You aren’t wrong, it wouldn’t be bad for it to just print the help in that case, at least when running interactive.
For automation, printing the full help of a more complex command would completely trash logs.
