Had a quick read, arrived at the same query as Michael did? If we are misunderstanding something, I guess the author should note it as a point thats misunderstood and give better examples.

"...the ordering is enforced by delaying the application of a write until all causally previous operations have been applied."

This assumes that _all_ causally-related writes will arrive at some point, which may not be the case (network loss without re-try, for example), and also assumes (I think) that all causally-related activities happen within the same datacenter (for example, what if "Bob" is replying via the Europe datacenter, but "Alice" is observing and replying via the US datacenter).

Again...quick read, but these things jumped out at me - I may have misinterpreted something along the way.
