Segmentation
If you define a segment “Page = page A”, then:
Considering the whole visit Page B (just one page visit): No page will appear in the segment
Considering the whole visit Page B → Page C: No page will appear in the segment
Considering the whole visit Page A (just one page visit): The page will appear in the segment (as you expected)
Considering the whole visit Page A → Page B: All pages will appear in the segment (as you probably did not expect)
Considering the whole visit Page B → Page A: All pages will appear in the segment (as you probably did not expect)
