Both scenarios he describes, where Earth was entirely depopulated due to nuclear war or climate change, would unquestionably involve the deaths of the people on the colonies as well, because they either a) could get no supplies anymore from earth, or b) they would die if they came BACK to earth.
Maybe, MAYBE this plan could work if the world population was wiped out due to a virus that killed everyone in a matter of weeks, and then was itself killed off due to a lack of living hosts ... in that case, we could potentially repopulate the earth from the people on the colonies, but with as many problems as we currently KNOW we face, it seems like a ridiculous expense for that extremely unlikely scenario ... it'd be much smarter/cheaper to plan for keeping a population alive here on Earth, with underground facilities built for that purpose.
