If a user begins a refresh-all action, then presses 'Back', the dialog disappears but the refresh continues. However, there is no indication that the refresh is still going on in the background (except that the list of saved pages shuffles around as new pages get refreshed). While one refresh is going on, the user can then initiate another (and another, and another). In this case, it seems like one refresh goes to completion, and then the next one starts. If a refresh-all is going on, the user should not be able to start another one. Ideally, the user should be able to cancel the (one) refresh-all that is going on, if it's taking too long, and there should be an indication (such as an animation on the Saved pages view) that there is a refresh still going on. (Also, pages should be refreshed from oldest to newest; it looks like the opposite is currently the case, meaning that the order of saved pages reverses with each refresh-all.)
Dismissing the "Refreshing saved pages" dialogue now cancels the update that's in progress. This may be because the issue was fixed since this bug was filed, but I'll just close this as WORKSFORME.
