The inside of my Specialized The Captain Control (front) and Fast Trak LK (rear) also look like that - I clean them out and completely replace the Stan's once a year. My bike came with the S-Works version of those tyres and touch wood, I still haven't had a puncture to date (over 4,100km's on my bike split over two sets of tyres). Yesterday I pulled out a few huge thorns when I was cleaning my bike - they'd pierced right through the tyre and you could hear the air escaping after I pulled them out. But I turned my wheel upside down, as mentioned by ctMTBer, so that the sealant filled up the whole and this morning my tyres are still well inflated ~20psi. I usually pump them up to 22psi before I ride. On the Stan's bottle, it says the sealant should last between 2 to 7 months, but that you may need to replace it sooner in a hot climate.
