Interchange keeps a historical list of the last few pages your
session has visited.  When you clicked on the 'buy' button in step 3,
the results.html page will have done a history scan and bounced you
to the last page it knows you visited.  Interchange expects this to
be the results page, but it is the flypage, because of your use of
the 'back' button and your browser's cache.

To change this, you could modify the [history-scan] tag in the
results.html page to exclude the flypage.  To try this, edit your
results.html and change this:

    [bounce href="[history-scan exclude=nothing]"]

on or around line 87, to something like this:

    [bounce href="[history-scan exclude='^/nothing|^/flypage']"]

Of course, this will only catch users who 'back button' from the
flypage.  A better solution would be to specifically look for the
results page and bounce there, like this:

    [bounce href="[history-scan find='^/scan|^/search' default=index]"]
