Well done this pilot - what a difficult decision to make!
Never heard of this 6 degree figure either. Surely the dynamic rollover point would depend on a number of factors (wind direction and strength, rate of movement, CoG ......)? I think the flight manual only states static figures (landing 8 degrees, shutdown 5 degrees slope).
A button to engage the autopilot on the cyclic would have come in really handy, especially flying from the left hand seat. The L2 has a fairly good layout with a spring loaded collective lock (which comes off by pushing the collective down) and a cyclic AP engage button.
