The computer mouse scroll wheel is a quadrature rotary encoder . It generates different data for forward scrolling and backward scrolling. For forward- 00, 10, 11, 01, 00 ......repeat  (red led blink )
                                        For backward- 00, 01, 11, 10, 00 ....repeat (green led blink)

Same problems as your first circuit. 00,10,11,10,11,10,11 gives wrong movement indications

After 11 it's 01 while going forward , it's a quadrature signal
