I would agree that there is no reason to change his classification (for whatever value that ever had) based on his presentation. Children find different outlets for their gifts at different times and in different settings. It may be that other aspects of life are sufficiently and pleasantly intriguing to him right now, so he doesn't need intense academic pursuits either to satisfy his need for stimulation, or to give himself an island of success in the midst of a sea of struggle (which, I think, is a change from some earlier stages of his development, if I recall correctly).
I'm happy for you and him that this year is unfolding so much more smoothly than has sometimes been the case!
