I've beaten this game twice and both times I blew up wade with a bomb. Never did I see a shootout, so it's not automatic it depends on how you played the level.
With the way the guide mentions it you can get it within the first minute of level 2 without any problems. Guides are always about the fastest way to 1k. Your method is literally the last level.
