Someone asked a question earlier in the thread about why he rolls left - ISTR the Germans lost a few 105s early on because, like the Lynx, there is a pronounced pitch/roll couple to the right.
This is noticeable when performing back flips and loops and can be demonstrated in a steep turn to the right. Opposite cyclic is needed to stop it rolling further.
I suspect therefore that he does the rolls to the left to give the best control margin for recovery.
On the other hand it may be to reduce the twisting loads on the tail boom/TR.
