A problem in "prefetch_L0_buffer.sv"

if (branch_i) begin instr_req_o = 1'b1;

      if (instr_gnt_i)
        NS = WAIT_RVALID;
      else
        NS = WAIT_GNT;
    end
    else
    begin
      instr_req_o    = 1'b1;

      if (instr_gnt_i)
        NS = WAIT_RVALID;
      else
        NS = WAIT_GNT;
    end

No matter what the state "branch_i" is, the following codes are the same, is there any mistake?
