BuddyPress.org

Yes it could be confusing and personally, I want replies posted in original blog and forum posts.

Network Admin dashboard – BuddyPress > General Settings:
choose option “Disable activity stream commenting on blog and forum posts?”

or, you can redirect the “Reply” button to the “Leave a reply” textarea in the forums, and so on in the comments:
