Storyline Accessible Video Controls seem to make accessibility worse?

Opening this conversation up to hear everyone's opinion. Being that Storyline accessibility checker strongly suggests (based on WCAG) to enable video controls when you embed a video, I'm wondering if this is not ALWAYS the best solution.

For example, if I am a screen reader user, relying on the information provided to me through audio, and there are two timelines (the main one and the video timeline) wouldn't this cause confusion? 

Furthermore, lets say you have set up some sort of visual where the video only takes up a certain amount(lets say 1/3) of the screen). On one side you have the video, on the other you have bulleted notes. Someone (using a screen reader or not) would click into there, meanwhile the main timeline is still playing!

The only conceivable idea where I think having the video controls could be applicable is when your video takes up a whole slide size running the duration of the slide.

Curious what I am missing from my thinking here, or what others think on this topic?
