Exactly!
One property of RESTful applications is that a client can enter the application at any steady state[1] and can understand that state in complete isolation (given it understands the media types of course).
RESTful clients proceed through an application one steady state at a time. They proceed from steady state to steady state by choosing which of the currently available transitions (links) they want to follow (given the overall goal they want to achieve).
[1] Steady state (==application state) is the state reached when all sub requests have been perfomred (e.g. in HTML land the steady state is reached when the Web page and all containing media has been loaded)
