I can't really go into specific depth and detail, however, net data sent to the client contains information that isn't necessarily used nor rendered (especially numerically) by the client in any fashion. In particular for snapshots of actions and statuses including actor source, target actor and attributes of what's about to be done. It's the basis behind how triggers using net data work and how things can be discerned well in advance before a mechanic needs to be resolved correctly because the message is sent before things are actually confirmed in-game by the server and client.
