He's right, Lifetime controls when the particle will delete itself from the game. SystemLifetime controls how long the particlesystem will keep spawning individal particles.
I don't know why the particles keep spawning until the end of the game. It is a common misconception that Lifetime, SystemLifetime, InitalDelay and BurstDelay are measured in milliseconds. In fact, they are measured in frames. In a 30fps game, 1 frame translates to 33 real life milliseconds. So your tornado should only spawn for 165000ms (165s or 2.75 minutes)
