Not certain how the views are counted, but I think it is likely that a reload or a refresh counts as one view....
I'm not positive. I always assumed it was individual views. I tried an unscientific experiment with a story I posted earlier today ... I found it in my posts so I could see the number of views. Then I opened it up, refreshed it, went out of it, refreshed it, posted to myself in it and did everything else I could think of to reload the page.
It stayed on 765 views (even when I refreshed the page where I was looking at the number of views).
I don't know if that means anything or not.
