It's not a flaw.
The propeller-looking symbol must cancel out exactly one mistake in the region it is surrounded by.
In the first image, there are no mistakes -- two stars are paired together.
In the bottom image, there are three red stars grouped together -- one extra. That one is incorrect, thus it gets cancelled out and the puzzle is solved.
But the first image IS a mistake (it is not a solution)
Two shapes plus same colour propeller= error
But that is not the case with the second image. There are two errors in there. One orange and one purple shape. The game flashes red only the orange and delets one. The purple should flash red too like in the first image.
