You are right - Posix.1-2008 says the same - '^' as matching reverse and
nothing for '!'

<cite>
A non-matching list expression begins with a <circumflex> ( '^' ),       
and specifies a list that shall match any single-character               
collating element except for the expressions represented in the          
list after the leading <circumflex>.
