If you mean by "undo last commit" reset HEAD pointer and index state,
then yes.

git-reset is all about setting the HEAD pointer, or to be more exact
to set current branch (current head) reference. There are three
degrees of it:
--soft changes only current HEAD
--mixed (default) changes current HEAD and index file
--hard changes current HEAD, index file and working tree
If you don't give <commit-ish>, git-reset defaults to HEAD,
i.e. current version. Thus "git reset --soft" is no-op, it does do
nothing.
