This is an interesting insight. The OP's constraint that no two adjacent squares are the same color ensures non-randomness. (Which reminds us why people are so bad at producing "random" sequences.)
Yeah, it’s a funny coincidence that all those constraints to make it look random produces exactly one solution. I guess the OP knows this is not ‘random’ in the mathematical sense.
