It reads like they saw the diagram from [0] and didn't understand what it meant (like, they assumed "x1" represented an entity like "Mary Lee Pfeiffer"). Note how in that diagram, the bottom nodes in the second and third layer aren't fully connected - which if you don't read the description, you could end up assuming the connections between layers are created and trimmed, not just weights changed. They may also be getting it mixed up with semantic search, where an entity like that would exist in a graph and have connections to related concepts.
