The name isn't all that obvious, but from what I recall of the original talk by Jake Wobbrock, he intended the recognizer to be very simple and easy to implement [edit: and computationally simple] (as opposed to HMMs or the like). This is alluded to in the pdf of the linked paper: "we present a “$1 recognizer” that is easy, cheap, and usable almost anywhere in about 100 lines of code."
