Sorry for the long delay.

This is the documented behaviour of revert-without-query.

   If the file name matches one of these regular expressions,
   then `revert-buffer' reverts the file without querying
   if the file has changed on disk and you have not edited the buffer.
                                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You could use

M-: (revert-buffer nil t)

(or a wrapper for that) if you really don't want to be asked, ever.
