That's just an oversimplification to avoid discussion. By that definition, a shortage is "real" even if it's been artificially caused by an interested party, because there's a whole bunch of people who really don't have access to whatever is in "shortage". "All demand is real demand" is true only when the demand is not intentionally manipulated.
