I think, only Org changes visibility, so it can track current state.

No, there are other commands outside Org that are changing visibility. Also, Org creates "strange" visibillity states with sparse trees etc. Furthermore, I in fact like that it is agnostic of the current visibility. Then I can create a state by quickly pressing TAB or S-TAB 1, 2, or three times - without even looking.

There is org-startup-folded that controls startup state, so org- mode should
know it.

Also S-Tab forgets state even in the middle of document. Key presses to
reproduce:

1) S-Tab - OVERVIEW
2) S-Tab - CONTENTS
3) C-G (or any other)
4) S-Tab - OVERVIEW (expected: SHOW ALL)

or

1) S-Tab - OVERVIEW
3) C-G (or any other)
4) S-Tab - OVERVIEW (nothing changed! expected: CONTENTS)

Is it by design? Why?

I don't think it is possible in general to know the startup state of a
file. Files with a #+STARTUP line may be an execption.

Hello.

On initial file opening, S-<TAB>    cycles through
1) OVERVIEW ->    2) CONTENTS ->    3) SHOW ALL
not depending on current state of document.

So, if (as default) document is in OVERVIEW state, first press
_does nothing_ (switch to OVERVIEW again). Expected: CONTENTS.

If document initially "#+STARTUP: content", then first press switches it
back to OVERVIEW. Expected: SHOW ALL.

So, S-Tab (and maybe Tab) doesn't use context state when start cycling.

Is it correct and why?

org-version 6.21 and 6.34c
Emacs 23.1.1

Thank you for your answer!
