It depends what the copycat was thinking, maybe they wanted to follow in Pollock's footsteps, maybe they wanted to showcase the point you're making, whether a copycat is as good as the real thing and therefore also considered art, perhaps even as important (apprentices often copied their masters, such as da Vinci's), maybe they are just creating it because it looks good. If there's no other reasoning, then I'd still say they're the same, because how can one say they're not art too? Even as an observer of the art, what if I like the copycat more? These are all open questions to the philosophy of art and I'm glad it's accessible today to everyone rather than only to the historically abled.
