I think he means that C-x r f should work as intended.  To fix C-x r w
accordingly you would have to write a new function, say
‘window-state-to-register’, based on ‘window-state-get’ and, when you
later jump to that register, use ‘window-state-put’ to put the state
saved in that register into the selected window.  Binding C-x r w to
that new function should then produce a register you can restore in a
later session.  Could you try implementing and testing that?
