Not quite.  From Documentation/git-rev-parse.txt:

    SPECIFYING RANGES
    -----------------

    Two other shorthands for naming a set that is formed by a commit
    and its parent commits exists.  `r1{caret}@` notation means all
    parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
    its all parents.
