Otherwise I will be very confused. If a searched string is not displayed in the window, I might think the searched string does not exist in the buffer.

Yes, and for a similar good reason. I don't really understand the insistence: you can easily cause the window to auto-scroll if you move point by one character. Emacs cannot possibly guess which part of the display is more important for the user in situations like this.

We only change the hscroll of a window when point moves, and in these two scenarios it doesn't move. I see no reason to assume that the user will necessarily want to have the window scroll, instead of keeping it at its current horizontal scroll.

(1) When isearch fails after last match
Evaluate the form below and type 'C-s a C-s', then emacs messages
'Failing I-search: a' and the buffer scrolls back left and the current
point is out of the window.
Type C-s again, and overwrapped search succeeds at the same point,
but the matched point is still out of the window.

Type 'C-c C-c' to view the source text and type 'C-c C-c' again to view
the image, then the buffer keeps scrolled right and the image is hidden
out of the window.

again, then the buffer keeps scrolled left and the current point is out
of the window.
