Emacs: dired plus still opens new buffer even with togle-dired-find-file-reuse-dir

Question

In emacs 23.3.1 on ubuntu 11.10, I have dired-plus installed. In my .emacs, I have:

(require 'dired+)
(toggle-diredp-find-file-reuse-dir 1)

When I press RET on a directory then C-x C-b, the Buffer List shows that there is only one buffer in use for dired. However, after I use ^, I have two dired buffers. C-x C-b confirms that there are two buffers: one for parent dir, one for child dir.

Is there anyway to keep the reuse work for ^ ?

Thank you.

I found one solution: using dired-single
