I don't think that's quite right. In both cases, the logic flow is

  1. Receive a request from the browser
  2. Decide what do do about it
  3. Tell the browser to enter a new state
  4. Wait for the next request from the browser

The difference is in the nature of (1) and the details of (2). I prefer to think about it this way:

For me, apart from style preferences, C::P works well where the validity conditions for entering particular states frequently depend on the current state. C::A is useful where the validity conditions for entering a particular state depend solely on the data requirements of the target state.

If a C::A app always required a parameter for "current state" along with the "run mode" and used that plus other submissions to determine the state entered, it would provide the same functionality as C::P. C::P just enforces that kind of thinking from the beginning.
