This is the way M-; has worked for as long as I can remember.
It also re-indents the comment, if needed.  If you want to uncomment,
then select the line via e.g. C-a C-SPC C-n and then M-; will do what
you asked for.

this appears to be like a bug.

in emacs-lisp-mode, if you have a comment like this:

;; This is a comment

and your cursor is somewhere on that line. Now, do comment-dwim, it  
doesn't uncomment the line. It just moves the cursor to the “T”  
in “This”.

Same behavior in cperl mode and probably all others.

I think this might be by design, but it seems counter-intuitive.
