These vertices look to be the insertion points of the screws.
All that being said, the webbing might be constructed differently than the perfect dual graph to allow for easier assembly and construction. Alas, what is perfect and elegant in the mathematical world, rarely works in the real world.
1. In graph theory, a dual graph of a given graph G is a graph which has a vertex for each plane region of G, and an edge for each edge in G joining two neighboring regions. This theory can be extending into 3D polyhedra geometry.

In layman's terms: Pretend the bolt heads are dots. Connect the dots. Some dots have 5 connections, some have 6. It makes a pretty cool shape made of triangles.
