Ah, ok. I think they're trying to balance 2 interests:
They don't want inflation. One of the impeti for this initiative is to have a currency that some politicians can't decide to print more of.
But at the same time, they can't just issue 90% of the total money that will exist right at the beginning. No one's going to buy into a currency where the vast majority of the "wealth" goes to a few early adopters.
So it makes sense to have the money supply grow fast at the beginning, when the currency is hopefully getting more popular as well, preventing inflation, and then to gradually slow down the money supply growth to achieve the goal of preventing inflation.
