YouTube Scroll by playback

Curiosity Ridge

I make Videos
Recently I've noticed "Scroll by playback" on YouTube. This must be a new thing as I didn't see it last week.
Does anyone know how YouTube counts a view? If a potential viewer just scrolls by my video and it plays for 5 seconds by they dont click it does it count as a view?

I hope not becauze that would cause my average watch time to plummet as I'm small enough that 10 or so "views" like this would destroy my average retention.

And if the user Is watching my video, at what point would I gain a view or watch time?

If anyone has info on this or there is a thread already created on this topic I would love if you, dear reader could share it.
