Yes, he realizes and it would have been easy for you to know by reading. He had a control group that also took IQ tests to factor out training effects.
I didn’t get that impression at all from ‘...for every point of IQ gained upon retaking the tests...’ but each to their own interpretation, I guess.
I just don’t see the feasibility in accounting for a practice effect when retaking the IQ test is also directly linked to the increased score you’re bound to get.
