Initial conditions differ, so the small error propagates as time passes. Imagine if you drive 1km/h slower than your friend. If you're driving for 10 hours behind him, the gap will be 10 km large between you 2. Now imagine you set multiple initial differences how that would work in time
They're oscillating at slightly different rates, but that translates into seemingly chaotic movement. With enough time, they'll eventually line up again.
Is there a reason, or is it truly random why?
