Right, which is why someone who's closer to being a novice, and maybe intermediates, will gain some strength. Beyond that? I don't see it, especially since nerual adaptations come and go rather quickly.
Of course, he could switch to a new set of movements just to try to get some neural adaptation on them.
Also, on exercises like squats, don't be fooled into thinking you're maintaing strength if you keep the same weight on the bar as you drop bodyfat, especially if you have a lot of fat to lose. Roughly 85% of one's bodyweight is against them while squatting. That means if you're lifting the same weight on the bar when you're 200 as when you were 225 (think - fat ass cutting down), you're not lifting as much as you were, 'cause though the bar weight is the same, your bodyweight isn't.
Not a big thing, but just interesting to point out.
