Pages are assigned into a PageGroup by calling the Page::setGroupName function. All pages initially start in a unique PageGroup (i.e., each Page is in its own PageGroup). If you pass the same string to setGroupName for multiple Pages, those pages will then be put into the same group.

PageGroups only exist within a single process, so PageGroups in one application will not affect or interact with PageGroups in another application.

No. This state is only stored in the current process. It does not affect other processes.
