It provides information about edge orientation. E.g. if the edge is in the UF position, in one orientation it'll be attracted to URF but not UFL and in the other orientation it'll be attracted to UFL but not URF. On average there'll be two attracting pieces on the left side and two attracting pieces on the right side (out of UF, UB, DF, DB), but sometimes there'll be a 1-3 split or maybe even a 0-4 split.I don't think it can provide any information, please correct me if I'm wrong.
