You have read the description for "branches_expr" carefully?

   It is the expression used by Zope to find the branches of
   the current object.

In your case, the expression is independent from the current
object. Therefore, it returns always the same branches (as you
observe).

Try:

<dtml-tree folder_of_things branches_expr="objectValues(['Folder','DTML Document'])">
....
