I would think that when there are clearly two completely different concepts when it comes to boxing out, by some of the greatest minds ever, it doesn't fall in the category. That was my point.
Wooden's resume speaks for itself. I tend to think the philosophy on boxing out becomes pretty trival on which is better if such records can be achieved by not doing it.
He didn't teach making contact with the opposing player at all, only to get in their way and go after the ball.
simply step in your opponents path, and go after the ball. Wooden's method, called called the check-and-go, might be best when your quickness and leaping ability are much superior to your opponent's.
He might be playing semantics, with it boxing out or not, but he doesn't mean seal the opposing player with body contact. Putting your body directly in the path of the opposing player and the ball seals them from it.
EDIT: I'll add on to it. I know I've told the story before, but my first intro to Wooden and this philosophy was in person listening to him talk at Hinkle Fieldhouse about 6-7 years ago. He said boxing out tended to turn into fighting for position, instead of fighting for the ball. Players would be so worried about making contact and holding them off, they would completely forget that the ball is needed to get a rebound. The aspect of boxing out became more important than the ball itself.
By putting your body between the opposing player's and the ball forced them to go around you or go through you.
