Let me put it this way and maybe it will make sense...
I will use an automibile race (nascar, F1, whatever suits you) to demonstrate the console race. The race consists of 500 laps, 100 to represent each of the 5 years of the console race.
Car 1 starts and is given a 100 lap head start. In racing, this would be near impossible to overcome.
Car 2 starts the race 100 laps (1 year) down in the race. By lap 190 (19 months after the race began when speaking of the consoles), car 2 has passed car 1. If this is not 'blowing by', I don't know what is.
