Indeed. When I was deciding how comment-line should work on a region, I specifically chose to not make it identical to comment-dwim.

Maybe it should still treat the "region ends at a newline" case specially. Some emacs commands do that already.
Not sure though, since that would be slightly redundant with comment-dwim.
