set false path

A mistake in my work:
      In the  synthesis script, we use the script below to set false path between each clock.
set _all_clks [all_clocks];
foreach_in_collection _clk $_all_clks {
 foreach_in_collection _other_clk [remove_from_collection $_all_clks $_clk] {
  set_false_path -from $_clk -to $_other_clk;
 }
}
       However, there are  two clocks with the same source(frenquence&phase) but different clock gatin cell , and we think they are the same in the design. So we need reset them.
      reset_path -from A_CLK -to B_CLK;
      reset_path -from B_CLK -to A_CLK;
