Yes, any user that can see your post can reshare it to people you did not originally share it to by clicking the share button.

They could also just tell person A or repost it if there wasn't a share button, though. Just use good sense.

wrong.. if you mark it as a limited share...no one outside that circle can share it..try it yourself and see...it is a new change that went into effect over the weekend

That's a good change, but that's not my point. My point is that things don't automatically become unprivate because there's a share button. Somebody has to make the decision to share these things, and they still have the ability to do so without a convenient button. The point is that users should still maintain good sense about what they post.
