Operationally the two ports are the same, both running in trunk mode using 802.1q encapsulation with a native VLAN of 1. If, however, the ports were changed to run in access mode, then Gi2/10 would be in VLAN 1200 and Gi2/9 would be in VLAN 1. The 'switchport access vlan 1200' command basically sets the VLAN that the port is in IF the port is in access mode.
