Why is it impossible? It's only "impossible" if cell phones have unique IP addresses. But, and I admit I've never tested this, my understanding is cell phones may switch IP addresses any time they reconnect to the network. And even if a cell phone does keep the same IP address for a long time, I'm confident that Apple is completely ignoring the IP address for each submission and taking only the encrypted location data. Apple has gone to great lengths to preserve privacy in so many other cases, it's outrageously nonsensical to accuse Apple of trying to match IP addresses with location data to identify individual devices (and besides, even if they did do that, all they'd know is the rough location history of some device, but nothing at all about what that device is or who owns it).
