You need to get a copy of "Handling the Big Jets" or some ATPL notes and have a read in them on Dutch Roll. To link the upper wing stalling and Dutch Roll is contrary to many other texts that I have read. Yes the angle of attack and corresponding lift production has changed between the wings however to describe it as a stall is a little extreme.
If you can't get hold suitable texts try doing a search of the Tech Log forum as there as been suitable discussions on this sort of topic in that forum before.
