I believe there are three terms which may describe what you're asking.
Cross Buy is the term used for a game which you can buy on one platform and receive the same game on another platform for free.
Cross Play is a term used for games which allow you to play with people on another platform.
Cross Save is a term used to describe the ability to move game saves from one platform to another and load the transferred save.
As for your example, I don't believe Alien Isolation fits any of these category.
PlayStation Trophies has a fairly decent list of Cross Buy/Play/Save Games if you want some examples of these terms.
