You have the right idea. But I wouldn't call it a decoy; rather I'd call it a set-up.
It's really more subtle than that. The origin of the sequence is in Seisan. We see it in Kanshu, but it's done with no step and they've added one more circle and a nukite. You sort of kind of see the relationship between it and what's done in Seisan, but the application ends up being different. In Seisan the subsequent final circle and nukite are done in a different direction with more stepping. So... it's just different. It's as different as saying you use a screwdriver to put the hinges on a door vs. using a screwdriver to make a repair on your car.
In Seisan the combination of the step forward, left circle, and right "chambering" for the hammer fist speak to me. It's one of those 90% solutions were no matter what you do, I'm going to be able to get inside and have my way with you. The step forward can be "the dragon's tail", getting inside the opponent's left front foot and breaking his center. The "chambering" for the hammer fist can itself be intercepting a technique coming from the left side, or could be part of breaking inside the opponent's stationary defenses. You could be contacting the person at one, two, or three points before you swing with the hammer fist.
My view of it is most definitely not what's in the "official" Seisan bunkai. That to me is just martial nonsense. Sometimes I think the choreographers just want to hide the good stuff from the gaijin.
