"the view in turn, asks the model for some data to display it"
This sounds to me like it's an (bad) explanation past the controller.
Anyway, the view never asks anything from the model. The view is the
final stage (a format, if you want). The most important thing in MVC
is the C. Without the controller it would be sorta procedural and so
the whole object model would be useless.
The example you gave is an optional one. 99% you wont need to use
requestAction if your controllers and model relations are well thought
out.
Basicly it goes like this: request -> load controller -> load models
-> call action (using models) -> assign data -> render view.
And requestAction does nothing else. So there is no direct
Model<->View connection, even so it looks like that. As you can see by
the URL (first param) it calls the "news" controller and the "view"
action - not any specific model
