Oh, I see the problem:

Try M-: (progn (set-window-start (selected-window) (point)) (goto-char 

and you'll see the that set-window-point wins even though it's run
before the goto-char.

That's why a sit-for works around the problem: it causes the
set-window-start to be "executed", letting the subsequent goto-char do
its job.

So maybe the right fix is to remove the call to set-window-start.
