Unfortunately not. BUt I believe that I found the reason:

FIrst: What do you get when you make
        man Top

Second: I believe that the man page is created in the line BEFORE the
changed stuff, so here:
  /* Look for the node.  */
  node = info_get_node_of_file_buffer (nodename, file_buffer);

  /* If the node not found was "Top", try again with different case,
     unless this was a man page.  */
  if (!node
      && strcasecmp (filename, MANPAGE_FILE_BUFFER_NAME) != 0
      && (nodename == NULL || strcasecmp (nodename, "Top") == 0))


in the 
         node = info_get_node_of_file_buffer (nodename, file_buffer);

nodename = NULL
file_buffer is something strange

from this we enter info_get_node_of_file_buffer where
        nodename = "Top"
because it was NULL, and then
        get_manpage_node (file_buffer, "Top")
is called.

And I assume that this returns the manpage for Top, which is here on my
system the same as man top.

REALLY HARD!
