As long as all of the slides in the presentation use the same theme, you need only one slide master. However, if you apply a different theme to some of your slides, you need another master, because a master can have only one theme applied to it at a time. PowerPoint automatically creates the additional master(s) for you, and they are all available for editing in Slide Master view.
