I guess this is one of the properties of wave motion? Correct me if I'm wrong, I'm intrigued.
I just need to confirm if there will always be a mirrored false contact. Thanks! :hmm:

That is correct. I can't quite remember the reason why this happens, but to ensure I always assign a tracker to the correct contact, I make a 10 degree turn and watch which one moves with the turn and which one doesn't. The one that doesn't is the true contact.
