So you did:

    git worktree add ../emacs-26 origin/emacs-26

which means "give me a worktree that shows the content of the remote
branch origin/emacs-26".  So it indeed didn't use any (local) branch for
that, and instead used a "detached head" (IIRC the terminology used by
Git).

You could have used

    git worktree add ../emacs-26 emacs-26

since you apparently already had a local `emacs-26` branch (which
presumably tracks the remote origin/emacs-26).

But as Andreas explains, it's easy to fix without a new "git worktree":
just do `git checkout emacs-26`.
