git rebase -i seems to have worked, but nothing has changed in the log -

i'm trying reorder commits in master branch. used following tutorial: http://blog.dennisrobinson.name/reorder-commits-with-git/

after saving changes in nano editor, terminal says:

successfully rebased , updated refs/heads/master. 

but when type: git log nothing has changed.

i not know if matters, i'm using linux mint 17.1
