YES! Generally, we have seen that the bits to the left give the broad range and as you move toward the right you narrow down what you're searching for. it's more a convention, the bits used to select the super page are chosen in the far left because they choose the super page, then as we narrow down what we're searching for we move further toward the right. The same idea is used with caches, where we go from index to tags to word offset and byte offset all go from the left direction to the right as we narrow down what we're looking for!
