Is it a bug where the uri has not changed, but the back button must be activated more than once?

Is it a bug where the uri has not changed, but the back button must be  
activated more than once?

or to put it another way, what events does the back button register,  
when the page has not changed?

how can one build an ajax app in svg and be certain that one hit of  
the back button will return the user to the site before they visited  
the ajax web app?

not the usual issue around being able to navigate within the ajax app.
