`--fixup=reword:<commit>` creates an "amend!" commit which

The commit created by plain `--fixup=<commit>` has a subject
composed of "fixup!" followed by the subject line from <commit>,
and is recognized specially by `git rebase --autosquash`. The `-m`
option may be used to supplement the log message of the created
commit, but the additional commentary will be thrown away once the
"fixup!" commit is squashed into `<commit>` by
`git rebase --autosquash`.

The commit created by `--fixup=amend:<commit>` is similar but its
subject is instead prefixed with "amend!". The log message of
<commit> is copied into the log message of the "amend!" commit and
opened in an editor so it can be refined. When `git rebase
--autosquash` squashes the "amend!" commit into `<commit>`, the
log message of `<commit>` is replaced by the refined log message
from the "amend!" commit. It is an error for the "amend!" commit's
log message to be empty unless `--allow-empty-message` is
specified.
+
`--fixup=reword:<commit>` is shorthand for `--fixup=amend:<commit>
--only`. It creates an "amend!" commit with only a log message
(ignoring any changes staged in the index). When squashed by `git
rebase --autosquash`, it replaces the log message of `<commit>`
without making any other changes.
+
Neither "fixup!" nor "amend!" commits change authorship of
`<commit>` when applied by `git rebase --autosquash`.
See linkgit:git-rebase[1] for details.
