Using the browsers back button to "backspace" to a previous page in, as you
have, a multi page form is at best fragile. It's totally up to the browser
what happens when you press it's back button. It might refresh the page from
the server. It might display the page exactly as it was last displayed. It
might display it as it was last downloaded. None of this is under your
control.

Every multi page form I have ever come across never even suggests that I use
the browsers back button. They all have two quite clearly marked submit
buttons at the bottom usually labeled [next] and [previous]. Sometimes the
previous button is also annotated with prose that sort of says if you don't
like what you see (on this preview page) then press me to "go back" to the
actual entry page.

This is, however, not a "back" button. It is a "go forward" to the page you
were on last. It might be implemented via a redirect status code so the
browsers history is sort of continuous bit it does *not* use the browsers
history, as the browsers back button does. It is all done server side, where
you *do* have total control over what you present to your user.

Do not rely on the browsers back button.
