My best attempt for now, based on my early understanding.
In go:
  • 4 apples 🍏 and 2 oranges 🍊
Out might go:
  • 2 green apples 🍏, 2 red apples 🍎 , a banana 🍌 and an orange 🍊
Basically it’s really hard to unpick which fruits are owned by who on the other side and how they were created.
In a regular coinjoin:
  • In go 4 apples 🍏 with stickers on of owners
  • Out go 4 apples 🍏 with no stickers on
