WTF??? Policing a Priority Queue

I was looking at how QoS on our routers at work is configured and I came across the following:

Policy Map QOS-OUT
Class VOICE-OUT
Strict Priority
Bandwidth 2700 (kbps) Burst 337500 (Bytes)
police cir 2712000 bc 339000 be 339000
conform-action set-dscp-transmit ef
exceed-action drop

Now I was confused I had always thought that you did not need to police on a priority queue because policing was built in to the priority command. The way I understood it was that as soon as you typed priority and then the bandwidth, that was the maximum bandwidth that would be allocated to the priority queue and so there was no need for a policer. Am I wrong has anyone else seen this configuration before? Is it normal and a case of what is actually used in the real world rather than what you learn from Ciscopress? Also which command would take precedence the police or the priority command if you set them to different rates?

When I asked why it was setup this way, I was told the police command was better for producing logging as the priority command just dropped packets and did not tell you if your priority traffic was exceeding the bandwidth you had provisioned. Therefore you would not know if you needed to increase your priority queue bandwidth. At first I accepted this explanation but then when I thought about it a bit more and did a show policy-map interface I got the information below.

Class-map: VOICE-OUT (match-any)
151522 packets, 13014864 bytes
30 second offered rate 0 bps, drop rate 0 bps
Match: ip dscp ef (46)
151140 packets, 13001580 bytes
30 second rate 0 bps
Match: access-group name VOICE-OUT
382 packets, 13284 bytes
30 second rate 0 bps
Queueing
Strict Priority
Output Queue: Conversation 264
Bandwidth 2700 (kbps) Burst 337500 (Bytes)
(pkts matched/bytes matched) 25068/1912731
(total drops/bytes drops) 0/0
police:
cir 2712000 bps, bc 339000 bytes
conformed 151522 packets, 13014864 bytes; actions:
set-dscp-transmit ef
exceeded 0 packets, 0 bytes; actions:
drop
conformed 0 bps, exceed 0 bps

Which to me showed that the priority command does show how many packets/bytes have been dropped. So I do not think logging would be the reason for adding the police command as well. I am leaning towards misconfiguration at the moment, but I would love to hear from people with more QoS experience than me to explain what is going on here.
