When he first reset back to the pre-modified state, the newly created
files were not removed from the working directory (this happens on soft
or mixed resets, fe, or when a branch is moved).

The files were untracked by git as seen from the commit he reset to, and
so git rightly refuses to apply another patch that introduces them, as
that would mean overwriting files git knew nothing about (again, at the
time of the commit he reset back to).
