The documentation is correct. Some builders will need to do CAL PLL on 160, others do it only on 40 meters. It depends upon the version of the firmware in the K2.
The second item on the errata sheet provided with the manual reads: "Page 9, first three alignment steps: These three steps are only necessary if your K2 firmware is older than revision 2.00. (With revision 2.00 and up, CAL PLL is done only once, and only on 40 meters, so there's no need to do it when installing the 160 m option.)"
