IIUC you eventually go to a window that was not part of the initial
configuration and there you move `point'.  Then you restore the initial
configuration and that last movement's value is lost.

I'm afraid that want you want cannot be achieved easily.  In principle
we'd have to record for each window the last position of its buffer's
`point' at the time the window was selected together with a time stamp.
When restoring the configuration we'd have to, for the selected window,
check whether its `point' should be moved to some youngest previously
stored position.  What if the window where the last move occurred was
deleted before restoring the configuration?  What if `point' moved at a
time no window showing the buffer was selected?
