why does documentation use "END CASE" when that doesn't work

[Susan Cassidy <susan.cassidy@xxxxxxxxxxxxxxxxxxxxxxxx>]

The documentation says:

CASE search-_expression_
    WHEN _expression_ [, _expression_ [ ... ]] THEN
      statements
  [ WHEN _expression_ [, _expression_ [ ... ]] THEN
      statements
    ... ]
  [ ELSE
      statements ]
END CASE;

And it repeats the "END CASE" phrase in other examples.  

However, that doesn't work.  You have to just use "END".

Shouldn't the documentation be fixed?
