It cannot. The protocol guarantees that the message is fully received.

So what is the purpose of this function being a bool, and why does most of the code check if it returns true?

Code == documentation
It has sense on the server side. The client reads server packets only.
Checks on client could be used to add a new data to a packet without increasing bitstream version, i think


CClientEntity* pCollidableWith = CElementIDs::GetElement(ElementID);
pSource->SetCollidableWith(pCollidableWith, bCollidable);
