For clarification, are you building your own flow for just educational/future purposes or some other reason (maybe you need multiple different conditions in different cases and don't want to bundle it all into one big Spring wiring mess)?

Just asking because that's basically what the context-check flow I included does.

No, that's recursive (the evaluate expression is telling it to repeat that same action-state).

What you want is an <end-state>, but you will need to put that <end-state> into conf/intercept/intercept-events-flow.xml and make sure your flow inherits from intercept.abstract.
