Model configuration overrides model data connection

[mccarty_amy-164]

When I configure a model, I can choose which data connections that model will access.

Let’s say I have model abc and it has access to 3 databases defined by: data connection 1 (dc1), data connection 2 (dc2) , and data connection 3 (dc3).

From these 3 databases, I have created multiple view files.
Views from dc1 are:view1a, view 1b, and view1c
Views from dc2 are:view2a, view 2b
Views from dc3 are:view3a, view 3b, view3c, view3d

In my model abc file, I set the connection parameter to connection: "dc1".
In this same file, I create an explore that uses view1a (dc1) and view2a (dc2). It uses views from 2 different data connections. 

Because my model configuration allows both these data connections, my explore works.

But why? What is the point of the connection: “dc1” in the model file if my model configurations override it? Am I missing something?
