S5720 port security

The documentation says: 
  • If a PC connects to the switch using an IP phone, set the maximum number of secure MAC addresses to 3 because the IP phone occupies two MAC address entries and the PC occupies one MAC address entry. The VLAN IDs in two MAC address entries used by the IP phone are different. 

But when I display the port MACs it shows only 2.

<SWITCH>disp mac-address g0/0/5
-------------------------------------------------------------------------------
MAC Address                  VLAN/VSI  Learned-From        Type
-------------------------------------------------------------------------------
1860-24e3-b7f8 503/-                             GE0/0/5             dynamic
487b-6b2e-902b 1503/-                            GE0/0/5           dynamic
-------------------------------------------------------------------------------
Total items displayed = 2

¿Is it really necessary to set the MAX number of MACs to 3? 

Thanks

As it turns out, it is not necessary, it works just fine with max number of MACs = 2, I have an S5270 with a few PC-IP phone combos, working properly.
