I am also not seeing it. These pictures strike me as exactly the kind of thing hipsters shoot as "street", graphically pretty strong, but from a safe distance and generally there's not much going on. They appeal because of the graphical qualities, the strong color, and because of timing - the shutter opens at the top of the jump, the instant the foot steps off the curb, and so on.
They're appealing pictures, for sure. But this stuff is pretty easy to knock out, and doesn't say much about anything.
As you can see from Adam's web site, the main difficulty with taking these photos is finding an uncluttered frame to put people in to. Cities are very inconveniently cluttered. When you can find an uncluttered wall with whatever light you favor in play, just stand there and shoot everyone who goes by.
