"The definition of stupidity is doing the same thing over and over again and expecting different results." — Albert Einstein
If someone cannot fly by jumping off a small cliff, it would not help them (and would be more dangerous) for them to try to fly off a big cliff. Mr. Clanger is essentially saying that playing Velios or Straq upfront would be like jumping off an even bigger cliff (than Saha).
To continue with the metaphor - we HAVE to continue jumping off A cliff (every Saturday), but no need to make the cliff a bigger one
And, if you can follow that metaphor, you can follow anything!
