Emacs Dired: weird behavior of `dired

The behavior I have is odd at best, but the situation is simple: given a folder test , I want to make a copy of it in another folder.

In practice:

Open Emacs, Mx dired in any folder.

+test to create a folder test .

+target to create a folder target .

Move on test then Ctarget/ to copy it in target .

So far so good, the empty test folder is copied as expected. Assuming there is some change in this folder, we want to copy it again to the same place:

Move on test then Ctarget/ to copy it in target .

Dired asks for confirmation to overwrite it, and if yes copies it again.

Now the weird behavior. With (setq dired-dwim-target t) :

Open a second window Cx 3

Move to target in this window, as to have target on the right window, but the initial folder on the left window.

In the left window, move on test and C to copy it again, DWIM will suggest directly target/ , so all that is needed is Enter.

Note that there is no question to overwrite it or not. Visiting target now shows the test folder, but inside it a second copy of test !

Even weirder:

Create an empty file in the original folder (Cx C-fbla, then Cx Cs to save it, and Cx k to kill it).

Select in the left window both test and bla with m.

C to copy them, DWIM will suggest directly target/ , so all that is needed is Enter.

Now it asks for confirmation and copies test together with bla in target as expected!

What am I missing?

(of course, this example mostly uses empty folders, but that's really just for the demonstration.)
