To tell you the truth, I don't know either.  The way I see it, M-j
should be bound to a function that funcalls comment-line-break-function
(whose default value is comment-indent-new-line).  So modes can modify
comment-line-break-function (ideally via add-function) to tune
its behavior.

I see now that it behaves differently because f90 tells it to, via
f90-comment-indent.  Try:

! bla
! bli

and then hit either TAB or M-; on the second line, and you'll see it
gets indented by 1 more space, just like in your example.
