I work on the Photos backend team at Google. Picasaweb and Google+ use the same back-end. The back-end makes no distinction between albums created in Picasaweb and albums created in G+. Having an option in Picasa desktop client to control whether an album is created in Picasaweb or Google+ would be nonsensical. I just tried creating an album in Picasa desktop client. I clicked on "Sync to web" and the album was uploaded and was available from both Picasaweb and in G+ Photos with identical functionality. I tried creating a second album, but instead of turning on "sync to web" I clicked on the "Share your album on G+" button. I 'shared' the album with myself. The resulting album is available in either Picasaweb or G+.
