OK, here's my understanding of how it works: Project status refers to the overall condition of a project - for example, a project that's on hold is suspended for awhile, but may become active again at some point. The dropped status is for projects that you don't intend to come back to.

On the other hand, view statuses refer to the "availability" of actions. Remaining shows all the actions that are still not completed; next shows the next action in each sequential project; available actions are the ones that can be done because their start date and time has passed. (They may be blocked if they belong to a sequential project and there are preceding actions that are still undone.)

A context can have a status because it may be temporarily unavailable for some reason. This can apply to a person or another resource.

(If I'm wrong about any of this, I'm sure the more experienced people will chime in.)
