Noparse tags?

Never heard of them.

Second because that is the way MathType organises it.

This is actually the exact example he gives in his video and certainly I think it's a great example. However, this example is not likely to click with viewers who are not yet exposed to vectors. I was suggesting only to add an additional example which remains in the scalar case.
