I think I didn't set the proper context in the diagram.
So this is probably has something to do with my poor explanation in the videos.
The diagram on the left is still considered dual-homed as a example because there are two possibilities of single points of failure: Either a link failure or a router failure in my example.
Though the router in this instance is a single point of failure. Here I was supposed to have elaborated on the fact that we eliminate every other single point of failure by adding multiple links and multiple ISPs.
So My first response was just looking at the router situation...not comparing to the upper right hand diagram where if you note-- we have multiple routers and multiple links but it is the router that will be the single point of failure on either ISP side or Enterprise side.
