My question is

1. why after I git stash apply

Answer 1

I think that something may be wrong in your configuration as while git stash records the state of the index and the working tree before resetting to the latest commit, git stash apply should only attempt to restore the state of the index if you use the --index option.

One possible point of confusion is that if you have conflict (i.e. there are merge conflicts introduced because the stash is being applied to a different commit where the files affected by the stash have been changed since the commit at which the stash was made), then if you use mergetool to resolve the conflicts, mergetool will automatically stage changes to the files on a successful resolution.

As Greg Hewgill states a simple reset will unstage all staged changes.

git reset
