I think that git checkout <commit> is a wrong tool here.
I personally would use git reset --hard <commit>.
Note that that command would also revert any local uncommitted changes
as well!

My view of the difference between the commands:
- checkout: stage[*] a change that would modify the current state of the
branch to the selected commit's state
- reset: change the current branch (its head) to point to the selected
commit

[*] by stage I mean modify the working copy and the index.
That is, if after git checkout you would run git commit then you would
commit a change that reverts the current branch to the selected point.
