'dired-revert' is spcecial.  There's nothing we can conclude from it.

As I suggested earlier we can use the position of the buffer's point
in every window regardless of whether it currently shows the buffer or
we later switch to the buffer in it.  But this is not what we usually
want when using multiple windows: We usually want them to show
different portions of the same buffer.
