It looks like the split condition happened at around the same time the engines were shut off.
Admittedly the departure from controlled flight as a result of the split condition is conjecture to some extent, but given the authority the elevators have it's got to result in a serious upset very quickly.
At any rate, the point I was trying to make was that in modern airliners, yokes aren't simply attached to a big metal bar like they were in the days of yore, they are complex electro-mechanical devices that can behave in unexpected ways when put into unusual configurations.
