Yes, however at any point in time there are no 8 snapshots which are 8 hours old. Only furthermost from any given point in time is 8 hours old and takes 20 GB. Other 8 are closer to the moment an hence their size is not 20 GB.
Yes, but the old 8 hours age snapshots are not kept. They are deleted. Once the closest snapshot becomes 2 hours old, the 8 hours old snapshot is deleted and therefore does not take up any space. At any point in time there are only 8 snapshots 8, 7, 6, 5, 4, 3, 2 and 1 hours old.
Yes, it should support 8 hours of changes, but why do you suggest that it instantly takes up 20 GB? Pointer based snapshots do not take up any capacity.

Each snapshot is 8 hours of data which = 20 GB of data. They need 8 snapshots at any given time. So 8*20=160 GB sounds right to me.
