I tried on 3 different systems, one of them GNU/Linux -- none of them
exhibits the behavior you describe.

A very simple interpretation: anything that needs to rearrange the
files in any way, by examining them together as a collection.

They don't do anything, because the list of files to display is
specified by the caller.

'dired' on MS-Windows _calls_ functions in ls-lisp.el, but is not
implemented there. And the behavior you described, which handles the
case of a list as the 1st arg, is not implemented in ls-lisp.el, it is
implemented in subroutines of 'dired' defined on dired.el.
Now, can we please stop splitting hair?
