[Matrix] If the agents can fuse body parts together (Mr. Anderson's lips.) Why can't they fuse his heart valves together when it matters?

Was this an inconsistency or was it simply an illusion?

They can... until you take the red pill. While you are connected to the Matrix and have an intact carrier signal the machines can kill you at will. They probably wouldn't melt your anatomy together (that's the sort of thing that freaks out bystanders enough to reject the program) but they could give you a 'heart attack' or convert you into an Agent.

Once Neo takes that pill he's largely disconnected from their controls and they have to resort to more overt methods like gunfire, which usually tricks people's brains into thinking they've died when they're 'shot'. Of course Neo eventually transcends that too, realizing that there are no bullets, just as there is no spoon.
