But OP is saying that you can then arrive 2 hours before the flight, and that it saves you 2 hours, last I checked the recommendation was to arrive 3 hours before.
I never had to wait 1hr for the initial security screening (and usually it takes me 15-20 minute tops from the terminal door to the duty free), that of course doesn't mean it cannot happen during peak times, but I suspect that if it does, other queues will also be clogged and so the recommendation will remain to arrive 3 hours before.
