I think restriction for poly are the same as for option --polygon-file, quote from doc: "If the polygon area(s) describe(s) a rectilinear area with no more than 40 vertices, splitter will try to create output files that fit exactly into the area, otherwise it will approximate the polygon area with rectangles.
