Points in Satire Sacrosanct

While I am by no means a movie critic, nor could I ever be a good one, I realized the other night that Rush Hour 2 uses a plot point that is from a Last Action Hero.  In Last Action Hero, counterfeit money is introduced for a short bit with its only "tell" being that when set on fire, it burns red.  Ditto for some counterfeit money introduced in Rush Hour 2.

Here's the catch.  Rush Hour 2 came out way after Last Action Hero, but Last Action Hero was a movie satirizing action movies.  So, let me get this straight, you used a plot prop borrowed from a satire?  It could be the one of the most genius movie moves, or the dumbest.  Luckily, only an inane nerd like me would notice.
