So, we could use for-loop after deciding the last index. But, we are preparing to expand num of sub-entity for MLO. Then, there won't be just two sub-entity. And, there might be holes between two bits in the bitmap. So, we cannot simply do for-loop as before. Instead, we need to follow the set bits.
