3570 Qos disable behaviour

Can someone who knows QoS on the cisco switch platforms tell me if the behavior below is normal as i dont think so!

Qos is diasble on the 3750 switch interface gi1/0/4 as the output below indicate right.

3750switch# sh mls qos interface gigabitEthernet 1/0/4          
GigabitEthernet1/0/4
QoS is disabled. When QoS is enabled, following settings will be applied
Attached policy-map for Ingress: SWITCH-TO-SWITCH
trust state: not trusted
trust mode: not trusted
trust enabled flag: ena
COS override: dis
default COS: 0
DSCP Mutation Map: Default DSCP Mutation Map
Trust device: none
qos mode: port-based

But I see queue drops expecially queue 3 incrementing and mls statistics incrementing and see lots of traffic ending up in the wrong queues for traffic with DSCP & COS 0. any ideas. IOS Code is 12.2(52) SE

3750switch#sh mls qos interface gigabitEthernet 1/0/4 statistics
GigabitEthernet1/0/4 (All statistics are in packets)
