I feel sharing makes more sense for posts than for comments, since comments usually need context to be valuable. There are very few comments I find that I feel deserve to show up context-less in the chatter feed of those following me. So maybe two buttons isn't a bad idea; one for sharing the comment with your followers, and one just for affecting the order of comments in the comment section.
