In my testing it actually seems to be worse than that.  In git.git:

    $ git log --oneline builtin/clone.c | wc -l
    99
    $ git log --oneline --reverse builtin/clone.c | wc -l
    99
    $ git log --oneline --follow builtin/clone.c | wc -l
    125
    $ git log --oneline --follow --reverse builtin/clone.c | wc -l
    3

So the combination of --reverse and --follow appears to have lost the
majority of the commits!
