A cursory understanding is a good starting point, even if it's not 100% technically correct. This is especially true for people who don't consider themselves mathematicians but still have to deal with quaternions or similar entities. The biggest stumbling block to understanding math (for many people) is a lack of confidence combined with feelings of frustration. If a simple video can get you over that first step, you are on a good path to developing a deeper understanding.
