I don't think what he has here is tightly coupled, per se, but the problem with it is that it has a high probability of errors (variable label not defined), since event.target in this case can very easily be a subcomponent of Button that might not have a label property (though I do believe if you click on the HBox itself you won't get this, since I _think_ Containers have a Label property for use with Accordions n such).
