You're missing the fact that you want to reset the index entry to the
state from HEAD. The working tree state is the modified one, and you get
that into the index using "git add". But you want the index entry to be
back at the state from HEAD. So HEAD is what you need to pass to reset
(well, actually, you can skip "HEAD" there, it's the default).
