Entry page is a visit-level dimension. From a backend table perspective, the entry page column persists through the whole visit.
When you make an entry page segment, that's bringing in whole visits where entry page = x. When you make a hit depth segment, that's only bringing in the very first hit of each visit. There should be no comparison between these two items, because they are not closely related to each other at all.
That sounds reasonable, but the top 3 "entry page" listed are "home page", "sales index", "event index" which are reasonable, the top 3 "pages which hit depth =1" are the very detailed content page about aftersales service.
