    $ git stash list

Do you mean this branch name? If so, no, afaik nothing in git stash needs that. It's merely a convenience for the user so they know which branch the stash was based on.

Correct, and it knows that by checking the parents of the stash (note that a stash is represented internally as just a commit):

    $ git cat-file commit stash@{0}                                                                                                                                                                          ∞

The first parent here is the commit the stash is based on, so that's what 'git stash branch' is using to base the new branch on.
