It's also irrelevant as anything other than a limiting case. The issue is with the statement that energy use must go up to produce more GDP or that not increasing energy use means we cannot raise GDP or even that GDP is limited by a flat energy use. USA GDP is still on basically the same exponential curve, yet energy is flat. That's the counter example. The rest is exposition.
