Even if it is implemented with continuations, you do not need multi-shot
continuations for that.
The real "interesting" scenario is when you open multiple windows into
the same session and play with them. E.g., you open the "next" form in
a different window (window 2), then press the back button in window 1
(one or more times), change some fields, go ahead again, and then switch
to windows 2 and from there you complete your transaction. This is what
continuations are supposed to "solve" (whatever your expectations ;).
