Sequential Segment Head Scratch - Pages seen in different visits
Hello everyone!
I have been trying for some time now to build a sequential segment that would accurately show the volume of visitors that saw page A in one visit then returned to page A in different visit. The goal being the show the visitor return rate to a page/group of page.
Now, if I stick to what is explained in the Adobe Analytics documentation for Segments on pages 30 and 31 (https://marketing.adobe.com/resources/help/en_US/analytics/segment/analytics_segment.pdf), I should only have to build a Visitor scoped segment, with 2 visits containers connected by a 'THEN' operator.
SEGMENT:

I get 85K visitors for the past 90 days with this segment.
Now my issue is, if I add the condition "AFTER 1 VISIT" next to the THEN operator, I get a lesser number of visitors (about 40K visitors). Although logically this should give me the same result of 85K visitors if my understanding is correct, since the original segment should have looked for visitors that saw the homepage twice in separate visits (so after 1 visit or more).
Additionally, I continued testing and found that if I switch the clause to "WITHIN 1 VISIT" I manage to get data too, for a total of 67K visitors. But wouldn't "WITHIN 1 VISIT" means that the visitors saw the same page twice in the same visit, which goes against what the original segment above should define?
