Mine does not (Emacs 21.2).

What Emacs does do that JED does not, is set a mark at the start of the
search and show a message "mark saved where search started".  So I can
search forward with C-s, go back to the starting point with C-x C-x and
then search backward with C-r.

You can do that in JED:

   % and zeros on the stack should match the value of m.
   % These 0s and 1s are used when unwinding the search stack
   % Since a mark was pushed and not attached to a character, push 0
-  
+   push_mark ();
    push_mark ();
    0;
    m = 1;

The drawback is that the marks are never popped - JED's marks are pushed
on a stack, Emacs has a mark stack too but doesn't keep reminding you
there is a mark with an "m" in the modeline.  See also message
