It did, but it still doesn't have the quickly-expiring content and fast interactions like Snapchat. Google+ was basically a Facebook clone but with more complicated sharing settings.
If anything, Google+ seemed to encourage people posting everything publicly. I didn't use it much, but I recall being able to click around into people's profiles and see a bunch of public posts, more than you'd expect clicking into a random profile on Facebook. I'm sure this was in part due to the fact that once they got people to merge their YouTube channel with their Google account, all your comments would show up as public G+ posts. Nothing about Google+ seemed like a private social experience to me.
