Conditional Debug doesn't work right, any ideas?

Conditional Debug doesn't work right.
I run the below commands on a cisco 7204VXR router.
I would think I'd only log output for snmp entering the interface
F0/0. However I see the requests from our server coming into the S1/0
interface.

What gives?

ro-ip#debug condition interface FastEthernet0/0
ro-ip#debug snmp pack
ro-ip#debug snmp head

ro-ip#sh debug cond
Condition 1: interface Fa0/0 (1 flags triggered)
Flags: Fa0/0
