That's just simulating how a player would currently spend his or her points (i.e. logically). My suggestion is that it's very much random. It might not be smart to have no focus at all on your spending of points, but it might be fun on a playthrough trying to adapt to or overcome the perks that are forced on you. Though I tend to get every perk on my playthroughs, it'd be a much different game if I didn't follow my comfortable, formulaic progression of picks.
