True or False: If a match expression doesn't match any case pattern and there's no default case, control falls through a switch statement. (learn.microsoft.com)

What does "control falls through a switch statement" mean in this context? Control just moves on to the next statement?

I thought if there is no match and a default case doesn't exist it will raise an exception. Is it not true?

I think even switch statement doesn't allow it [...]

A switch statement allows fall through when the case itself doesn't have an implementation.

For example this is also considered a fall through:

        switch (x)
        {
            case "One":
            case "Two":
                Console.WriteLine("One or two");
                break;
        }
