As another said it is referring to LAG (Link Aggregation Groups or "EtherChannel").
From a logical construct perspective each "2x100G" interface is represented by a single "200Gbps" layer 3 interface. When referring to 2x2x100G, it really is meaning 2 layer 3 interfaces, consisting each of 2x100G ethernet interfaces in the link aggregation group.
Hashing of L3/L4 header data provides for consistent flow -> lag member mapping to avoid OOOs and other historical multi-link issues.
