To me, it looks like abnormal wear. After 26000 km on the road, mine (sram force 22) are still very similar with the new ones, just the edges are a little bit less firm. And I use to heavily shift, to keep a constant cadence.
I had to change the whole derailleur for a new "middle cage" to accommodate bigger cogs (11-32), otherwise I think the old pulleys would last well above 100.000 km
