Hmm ok, yeah, I see where I went wrong on my segment... I also tried an example using yours....
Yours looks like it should work, I tested it with a page on my site, mine, once I added the container broke some of the logic... because the first hit of the page (the included part) didn't exclude the potential additional hits of the page subsequently in the Visit... sometimes the way that segments work can be a little frustrating 🙂
The segment logic can sometimes cause some havoc, but with something like "Page" which is only on page views and acts more like a Prop, makes this easier to work with.
Hi,
I found a way to validate the logic of my segment to have a specific page seen only once:

How :
1) The number of visit of the page in my segment has to be equals to the total number of visit in my segment (in red). So I'm sure all my visit contains this page.
2) In my segment, the number of page views on this page has to be equals to the number of visit on this page (in yellow). So I'm sure the page is viewed only once

Hope it can help the others ones.
Thanks Jennifer for your support
