UAF12 — Two model kinds are addressing modeling of connections

According to UAF v1.1 §7.1 table 7.2, two distinct model kinds are addressing the modeling of connections; Structure and Connectivity.

Structure: Describes the definitions of the dependencies, connections, and relationships between the different elements.
Connectivity: Describes the connections, relationships, and interactions between the different elements.

While §1.3 emphasizes the Separation of Concerns supported by a framework.

Are we addressing the same type of connections.
If not, it should be precised there.
If yes, what about the separation of concerns?
