Yes, it is fairly obvious that his method is used but simply because no better alternative exists in other equipment.

In other words he expects he needs no thermal gain and flies a best glide. Set MC = 0 and the problem is solved. The moment his tactic pays off he has his target in glide range and thermalling drift calculations don't even enter the picture.
