library_setup_time puzzle

aaronhe

The followint is a slice of timing library.
  
  .........
  
  pin(D) {
    direction : input;
    nextstate_type : data;
    related_ground_pin : VSS;
    related_power_pin : VDD;
    capacitance : 0.0009724;
    rise_capacitance : 0.0009724;
    fall_capacitance : 0.0009669;
    timing () {
      related_pin : "CP";
      sdf_cond : "SDN_SDFCHK";
      timing_type : setup_rising;
      when : "SDN";
      rise_constraint (constraint_template_3x3) {
        index_1 ("0.0075, 0.0917, 0.7657");
        index_2 ("0.0075, 0.0917, 0.7657");
        values ( \
            "0.05026, 0.07239, 0.1913", \
            "0.02122, 0.04428, 0.1612", \
            "-0.06691, -0.04752, 0.05172" \
        );
.........


index_1 is the related_pin_transition ( the transition of CP pin?), index_2 is constrainted_pin_transition (the transition of D pin?);

My question is what's the order of index_1 and index_2 for values ? How I can get this information from library?

If the following order is right (see the figure), why the library_setup increase with index_1(clk pin transtion time) increase, but decrease with index_2(D pin transtion) increase.
In my opinion, the setup time should increase which the increase of D pin transtion time and decrease with the increase of CP pin transtion time.
