Why the noise sizes for sub-generators are not the same?

Thanks for sharing the source code. I am wondering why the noise sizes are not the same for all sub-generators (see my code below)? Is this intentional? Maybe I missed something in the paper.

batch_size = 500
k = 10

for i in range(k): 
    start = int((((k + (k - i + 1)) * i) / 2) * (batch_size // block))
    if i < k-1:
        end = int((((k + (k - i)) * (i + 1)) / 2) * (batch_size // block))
    else:
        end = batch_size
    print(i, start, end, end-start+1)

0 0 90 91
