I'm not sure whether that helps or hurts his point about the complexity of the "collapse". The Mycenaeans had a large scale trade empire across large parts of the Mediterranean, from Italy up through the Black Sea. The "collapse" involved other "civilizations", including the Hittites, Assyrians, Babylonians, and Egyptians, all of which were relatively tightly bound by trade and diplomacy.
The only commonality, as I understand it, is that between 1400 and 900 BCE, all of that trade and most of the "higher" civilization in those areas disappeared, to eventually be replaced by something different.
The Minoan civilization disappeared (possibly being partially incorporated into the Mycenaeans') about 300 years before the disappearance of Mycenaean culture along with the other late Bronze age hullaballoo. https://en.wikipedia.org/wiki/Late_Bronze_Age_collapse
