Because 'continue' and 'retry' are not the same thing. 'continue' means go  
to the next iteration, and 'retry' means repeat the same iteration.

....CONCEPTUAL CODE....

    for_start:
        init_code;
    for_test:
        if ( end_condition ) goto for_end;
    for_body:
        do_something;
        if <A> goto for_index; // continue
        if <B> goto for_test; // retry
        if <C> goto for_start; // restart
        if <D> goto for_end; // break;
    for_index:
        update_index;
        goto for_test;
    for_end:
