Yep - I've done the ST1300 answer for the ST1100 question. The same logic applies though. I used to insert the stopper bolt loosely and tighten the axle bolt first, and it was pointed out that was wrong. So I tried to work out why it was wrong. The above is the reason that I came up with - tightening the axle while the stopper bolt is still able to rock on its threads - casues the issue that I described.
