AC can use hundreds of NPCs at the same time. Also, the entire game world is built from elemental components in order to facilitate the freerunning traversal. The large number of NPCs is only possible because of heavy re-use of textures, meshes, animations and other data, too.
The Division has no need for either and thus it's probably allocating resources and implementing game assets in a very different way. You have to understand that AC has far more constrains and thus it has to make trade-offs, possibly to the point that there's no upside to leveraging the features of the Snowdrop engine.
Watch Dogs may be pretty similar in principle, regardless of its implementation. For example, it seems that nothing is working in the Division - no public transport, no lighting at night, no communication networks and so on. Once again, different trade-offs that may have a fundamental effect on how the game and rendering systems are built.
Ubisoft is like the second or third biggest publisher at this time. I'm sure they're looking pretty deeply into leveraging existing technologies, far more than what we can do here using publicly available information. I would not argue with their decisions...
