This function determines if you are allowed to walk down the stairs or level teleport from the quest home level, but does not govern branchporting. Qstat(got_quest) means if your quest leader has irrevocably given you permission to proceed, and is_pure(FALSE) is an alignment check. Qstat(got_thanks) is only relevant if you wish for your own quest artifact in wizard mode and then throw it to your quest leader without going through the usual dialog with him. It is set in finish_quest(). (The dialog would set Qstat(cheater), but that doesn't seem to be referenced anywhere else.)
