I can see that. Both Caesar and Catiline sought power through extra-constitutional means. Caesar surely took notes (and Cicero thought Caesar even secretly supported Catiline). They were all in the senate together under Cicero's consulship, after all. They were all hyper-ambitious patricians. The conservatives (optimates -- the best) regarded the populares (the faction Caesar aligned himself with) as people willing to threaten the order of the state by pandering to the masses. This is what Catiline did, and Caesar too. This was the basic threat that the Gracchi brothers appeared to present in agitating for land reform and something that underscored Caesar's political agenda (he had to find land for his loyal veterans).
