Roundabouts differ wildy in design, sometimes a separate bike path is better and sometimes its better to be unseparated. In my experience (I've biked in several European countries) the most important parts of unseparated roundabout biking is to take the lane (to reduce the right-hook risk) and signal clearly. About the video; the thing that sets Netherlands (and Denmark, IIRC) is that bike lanes have right-of-way. Separating bike traffic into a generally slower infrastructure, and then slowing it down further by giving cars right-of-way is contraproductive - if the goal is to increase biking.
