Example - see this rock.  How do you figure out where the feature scale of the texture is alongside the feature scale of the rock itself?  Then, what makes it look like a rock?  How does the large (lead-in) scale relate to the smallest scale?  It's stuff like this that makes it difficult for me to say it is clear to use that definition.  On a practical scale, just playing with the clouds or rocks shows me what things mean, but I certainly wouldn't say that saying it this way would prevent confusion when anyone think they can actually create a scene understanding that definition.  
I do see the analogy, but not the definition.  It might seem like a small difference, but not to me - it's everything to understand what you're doing when you are trying to create something...a large analogy like that might be entry to understanding the concept, but not the practice.
