Cool project. I think what they were talking about is demonstrated here. For example, in Construct when you want to add an action to an event you click the add button then a wizard pops up to help you assign it. If you know how to program that is annoying because you know how to express yourself faster with text. If you don't know how to express yourself it provides the scaffolding to help you succeed. I think they are lamenting that for experts they haven't seen a visual language that is faster / more expressive. I don't think they would argue that this isn't easier for beginners.
