I don't think it is, I highlighted "in pure driving terms" that means that he was very good at driving, pity he wasn't very good at the rest and so he didn't achieve much in his career whereas his brother, who

Driving is only part of the job of a racing driver, he needs to be able to set up his car, deal with the team, deal with outside pressure, be able to focus and use any available chance and most importantly
race his fellow racers. Jarno Trulli was quite good at driving but he was also known as the "moving chicane", driving is only part of the game
