I was talking to Dana, aka the man with the goggles, the other day about the video. It was not their intent to recommend making a starter for dry yeast, only to demonstrate how one goes about making a starter. Their choose of dry yeast was purely economics, $3 for dry and $8 for liquid. They felt Home Brewers advanced enough to consider making starters would know that dry yeast doesn't require, nor should it utilize, a starter.
Alas, they made assumptions and that is never a good thing but their intent was good and I still like the video. I wouldn't hesitate to recommend it but I would qualify it with "Use liquid yeast only, dry doesn't need a starter" and "Use foil or foam, not an air lock, your yeast will be happier"
