The edit-conflict resolver doesn't care whether you're editing the page or a section. If the two edits are to different lines, they're merged; if they're to the same line, they conflict. (There may be some more details that I don't know of, but that's the gist of it.) Edit conflicts occur most frequently on busy RFAs or talk pages because everyone's editing the same line, namely the one below where the last guy left his comment.
I would probably mumble something about my long-ago proposal to do away with the "Edit Conflict" screen altogether, if only it hadn't been criticised and flamed so much at the time....
