They used a 48T big ring since most people are unlikely to "need" a gear bigger than 48/11, thus they can use a slightly tighter gearing in front. Compact cranks almost always use a 110BCD for both rings, limiting you to a 33T inner. I guess that's better than the days where you couldn't have anything smaller than a 42T...
