mistaking switch expressions and switch statements

[Mateusz Romanowski]

Hi,
I am reading article "Design implications of Java’s switch statements and
switch expressions" [1] by Vasily STRELNIKOV .

I am confounded by "*Figure 6.* Handling complex situations with a Switch
Expression" which I believe is a new-style Switch Statement as the `default
clause` is removable even though Switch is not total.

Could you confirm my interpretation?
And should it be correct, help to contact author to ask for correction.

Cheers,
Mateusz Romanowski
