On my 2011 Plus4, the top grease nipple takes many more pumps than the bottom nipple, before the grease oozes out.
Can I suggest that you remove the wheel so that you get a better view of the suspension whilst you grease the suspension and you should see the grease oozing out.
Remember to wipe off any excess grease to ensure you do not get any on the brake disks.
