What the passage does
Two five-second passages meet. Each supplies the same line drawing. At the join the page replaces the drawing with an identical copy; it adds no visual mark for that event. The total duration is ten seconds.
Time while the page is hidden is excluded. Browser timing is approximate. A visit is neither stored nor sent. This construction does not establish that a viewer notices or fails to notice a join.
