From what I remember, there shouldn't be a functional difference. The difference is the amount of feedback delay in the loop. You always need to make sure one delay exists in any feedback path you can take, to avoid race conditions. After that, you want to minimize the loop delay. The one accumulator with delay in the feedback path ensures stability. The other accumulator keeps the delay out of the feedback path because it minimizes the loop latency.
Hope that helps.
