Nursery Stock Series Pt. 3: Bar branch?

In the Nursery Stock Series Pt. 3, Ryan creates a really nice looking Fir Bonsai- at the end, it seems like we have a bar branch as the bottom-most left and right branches. Bar branches are a no-no in fundamental bonsai design- is there a reason why it can be kept in this case?

If I remember well, there was a very significant root coming off it.
