Looks at every AS path observed for a prefix and reports the ones that do not fit. Four patterns are checked. A path loop, where an AS appears twice with other ASes in between, which prepending does not produce and a leak does. An unusually long path, measured against the median length of all paths to the same prefix rather than a fixed number, because path length is a property of where you sit in the network.
