Docu bug in CASE Statement

I would say you have a docu bug here (first example):
https://mariadb.com/kb/en/case-statement/

END CASE -> END only

SQL> SELECT CASE ROUND(RAND()*3, 0) WHEN 1 THEN 'Value 1' WHEN 2 THEN 'Value 2' WHEN 3 THEN 'Value 2' ELSE 'All other values' END CASE;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'CASE' at line 1

SQL> SELECT CASE ROUND(RAND()*3, 0) WHEN 1 THEN 'Value 1' WHEN 2 THEN 'Value 2' WHEN 3 THEN 'Value 2' ELSE 'All other values' END ;---------------------------------------------------------------------------------------------------------------------------------------

Possibly a Copy/Paste error from other source?
