Yes indeed, what I thought was for example but not limited to the following:

You could create your first Kickstarter for a new project where you add higher tiers (above the initial pledge goal) for more content, features and the like. Now, when you for example reach the pledge goal but not the higher tiers, you can create the basic game first and meanwhile ask once or multiple times for additional money again, showing your progress of the game so far and maybe even release it already to the initial backers (which may then back your game again too).
