Paper C 2012 - The solution according to the exam committee

Earlier today, the EPO published the examiner's report on the EPO website. According to the exam committee, the correct attacks are:
Claim 1: Nov A3, Nov A5
Claim 2: A2 + A6
Claim 3: A4 + A5 and A4 + A6
Claim 4: A3 + A4
Claim 5: Nov A3, Nov A5
Claim 6: Inv A4
Claim 7: A6 + A5
A quick comparison to my own solution tells me that I can agree on almost all attacks. I am, however rather shocked by what the exam committee did at claim 3.
