It's not easy to guess if red rubberband is the new or old geometry and which one will be actually replayed.
I would choose blue for new geom and maybe (not sure) orange for old one.
A text legend could be set in next to the "geometry" frame with something like:
geometry - orange = old / blue = new geom (will be restored when replaying event)
