Yes that’s the way it supposed to be. The homepage (on most Genesis themes) is designed to show the blog if there is no content inside the widget areas. As soon as you add content in any of the widget areas for the homepage it will show the homepage template. You can look at the demo for an example – http://demo.appfinite.com/epik/
The easiest way (without having to deal with code) to add posts is to add the Genesis Featured Post widget inside one of the homepage widgets.
