No I get that.
My thought are, you out an album in private to never share - no sharing of any, no link generation.
Public to share images - you don't care if people see all in the album, so have a spot to show images in album
private with link - you might want to share one or two images here and there with others, but you don't want user x to see half the images there, so no other images in album spot at the bottom of the page
