The only thing I can think of is that he might have taken it to the shudder prior to RBS and held it just under - It’s hugely pronounced in the Lama. The higher you go the worse the shudder gets. You’d have to deaf, dumb and blind to get to the pitch and roll.
But, as you know better than me? Losing airspeed in IMC is as dangerous as exceeding VNE, so I guess he would have kept it on the back edge of the shudder, which makes me shudder just thinking about it?...
Let’s see! IMC, No Starter motor (taken out after start to save weight)
Reputedly no fuel anyway:

Auto in IMC with no ASI and a vacuum driven Attitude Indicator ?
But there again, Jean Boulet was no stranger to high altitude, and well prepared for the task by the standards of the day!
