Discovering the same flaw

Tonight I played the Holiday Ghost Bot as black this time, and discovered the same flaw from before when I captured its queen using my knight after playing a certain number of moves!

I know how to defeat this AI because I beat it before, but this is another example of exploiting weakness because computers have them too, which makes it possible to defeat it but these are usually intentionally programmed into the AI to give the player a tactical advantage if discovered, which is why Garry Kasparov won the 1996 mach against Deep Blue because he found a way to beat it, but then lost the rematch in 1997, but I don't think it was part of its programming to have a weakness or flaw in the first place, but computers do?
