[CQ-Contest] KP2MM Disqualified in ARRL CW 2012

[yuriy rakushchynets]

Hello to all 
I was operate in ARRL CW using KP2MM (club call)  trustee KV4FZ.  I have General class licence.
And Kutzko KX9X told me:

Yuri-
 
You were disqualified from the 2012 ARRL DX CW Contest for operating out of band.
 
 
ARRL Contest Rules state:
 
2.1.Entrants agree to be bound by the provisions and intent of ARRL contest rules.
2.2.Entrants agree to be bound by the regulations of their national licensing authority.
3.1.All operators must observe the limitations of their operator licenses and station licenses at all times.
 
You hold a General class license. Your log shows significant time on 15 meters below 21.025, on 40 meters below 7025 KHz and on 80 meters below 3525 KHz, which is outside the General class band

And i second email:
KV4FZ’s presence is irrelevant. You entered as a Single Operator, and you are a General Class licensee.
 
You are the Control Operator in a Single Op log.
 
As a Single-Op, you must operate under the limits of your license.
 
If KV4FZ was your Control Operator, you are no longer a Single Op.
 
You entered as Single-Op and did not meet the rules requirements. Therefore, you are disqualified.
 
73,

Sean Kutzko, KX9X
Contest Branch Manager

My question why i was disqualified if i operate under Extra class privileges and control operator was there all of the time. And WHY i should be in MO entry if control operator did not help me. ( Some times wife brings you coffee and you go to MO entry?)
I don't feel like i broke FCC or ARRL rules.
I was operate in many contest and never got this before, but now when i clam high score Unassisted is happening. Of course, the easiest way to pass the Extra class exam, but I wonder if I violated any rule or, or not?
Need your opinion
