I don't understand something about the track permutation problem

hello，I've read the paper on EINV2, but I still don't understand the orbital alignment problem. Does SELDnet's output format also have this problem? Can you give me an example to help me understand, thank you very much for your reply.

I have another question: For example, sound events A and B are detected in a time period, and at the same time, two sound event coordinates X and Y are detected. How to determine the coordinates of sound event A is X or Y. Looking forward to your reply
