The Chest stuff goes first, so you're not doing Back work first, as fatuiging it may hinder the Chest work, as the Back helps to stabilise and support the Chest work.
The Preachers go last, as big muscles are better before small ones. Row work uses Biceps anyway, so doing Preachers afterwards will fatigue the Biceps a bit, but without having any potential to affect the Rows, like they could if done before.
Make sense?
