Are you sure that you didn't mean yes and yes?
As the transcript shows the git-diff form produces a
backwards diff. Thus to get the same output git-log
needs the -R:
$ git init
$ perl -e 'for (0..10) { print "$_\n" }' > file
$ git add file
$ git commit -minitial

$ sed -e 's/4/four/' < file > file1
$ mv file1 file
$ git commit -a -m'updated'
