I haven't read too many of these reports so this may be just standard
stuff, but it seems odd to me. They already determined the wings came
off in flight, why does it mater if the engine quit or not. The end
result would have still been the same.

Sometimes the obvious is not the whole story or even simply wrong. It's
essential to adhere to established procedures in investigations as well
as in the cockpit.
