It means that all of these do the same thing ...

	git commit --fixup=amend:<commit>
	git commit --fixup=amen:<commit>
	git commit --fixup=ame:<commit>
	git commit --fixup=am:<commit>
	git commit --fixup=a:<commit>

... until somebody more brilliant than either of us comes along and
invents another operation that sits next to 'amend' and 'reword',
say, 'annoy'.  At that point,

	git commit --fixup=a:<commit>

no longer uniquely identifies a choice among three ('amend',
'annoy', or 'reword') and you'd give an error message, but

	git commit --fixup=am:<commit>

will keep working as an abbreviation for "amend".
