Actually, all +1 votes, whether or not made by your friends (and regardless of their +1 sharing preferences) may contribute to the total +1 count for a particular piece of content.
From google: "Regardless of whether you chose to publicly share your +1’s tab, your +1’s will still be visible to others viewing the content you +1’d. For instance, your +1 could appear as part of an anonymous aggregated count of the people who have also +1’d the same thing"
