Popping my head in as the person that originally wrote much of the
parser+highlighter code ;-).

Reserved words originally referred to keywords that got highlighted
specially, while forbidden words were those that the MySQL parser would
throw an error on.

All forbidden words are reserved, but not all reserved words are
forbidden.

reserved & forbidden => always highlight as keyword
reserved & !forbidden => highlight as intelligently
!reserved & forbidden => invalid state
