Those vertices weren't grid-aligned because they were drawn with the ellipse tool which won't snap to grid. In my experience there's about a 50% chance of UDB doing the wrong thing if you let it try to autoclose a sector involving non-grid-aligned vertices, so it's best to go ahead and include those yourself, because your new vertices will snap to the existing ones and then everything will line up/connect properly. Hopefully that makes sense.
Can I make a suggestion? There are some software that render your keypresses to the video, this would make it easier for people to read what you're inputting. Thanks for the great content!
In 1:07, why did you outline the then-external linedefs?

Thanks so much for demystifying these!
